Prognoza ceny bitcoinów: BTC do 30000 $, analityk

Przewidywanie ceny Bitcoin przewiduje spadek do poziomu 32000 USD.

Silny opór znajduje się na poziomie 37500 USD.

Silne poparcie znajduje się na poziomie 35500 USD

Król kryptowalut rozczarował traderów, ponieważ nie był w stanie przebić rekordowego rekordu sięgającego 42 000 USD. Król na razie schodzi w dół. Bitcoin osiągnął szczyt na 24-godzinnym wykresie cenowym na poziomie 39.840 $ na samym początku dnia, ale tylko po to, by zejść do 24-godzinnego minimum na poziomie 34.400 $. Po nabraniu rozpędu król znalazł stabilność w przedziale 36 000 $. W chwili pisania tego tekstu wartość Bitcoin wynosiła 36 743 USD.

Rynek Bitcoin jest zwyżkowy. Spośród wszystkich wskaźników technicznych 14 jest w stanie kupna, podczas gdy 9 wskazań jest neutralnych, a pięć wskazuje na sprzedaż. Spośród wszystkich wskaźników oscylatora większość jest neutralna, z jednym wskazaniem sprzedaży i dwoma wskazaniami kupna w momencie pisania. Spośród 17 średnich kroczących 12 podaje wskazania kupna z czterema wskazaniami sprzedaży i jednym neutralnym.

Przewidywanie ceny bitcoinów: czego się spodziewać?

W swojej prognozie cen Bitcoin , analityk Alan Masters stwierdza, że ​​niedźwiedzie wygrały dla króla kryptowalut, ponieważ Bitcoin obniża się, aby ustanowić niższe szczyty. Po kilku dniach śledzenia kryptowaluta zaczęła nabierać rozpędu, a analitycy byli pełni nadziei; wydaje się jednak, że król zawiódł wszystkich. Analityk uważa, że ​​cena Bitcoina ma podążać za niedźwiedziem i zanurkować. Względny wskaźnik siły (RSI) i dywergencja średniej ruchomej konwergencji (MACD) wykazują tendencję spadkową, co dodatkowo napędza bessy.

Masters uważa, że ​​Bitcoin stoi w obliczu spadkowej linii oporu, która zepchnie Bitcoin w dół. Bitcoin wcześniej testował EMA-21, zanim osiągnął niski poziom; według analityka oznacza to, że Bitcoin będzie teraz testował następną wykładniczą średnią ruchomą (EMA) jako wsparcie, czyli EMA-50 (w kolorze ciemnoróżowym). Następna cena docelowa kryptowaluty może wynieść 27 795 USD, czyli na poziomie EMA-50. Poziomy zniesienia Fibonacciego na poziomie 0,382 (32,151 USD), a następnie 0,5 (29,109 USD) i 0,618 (26 066) również będą działały jako silne poziomy wsparcia. Jednak analityk twierdzi, że jeśli cena Bitcoina zamknie się powyżej 36180 USD, analiza zostanie unieważniona.

Trader: it’s not the end of the world if Bitcoin doesn’t break new records for a while

According to trader Brian Krogsgard, a period of sideways price action could be healthy for Bitcoin

After rallying above $40,000 and a correction that ended near $30,000, Bitcoin (BTC) has rebounded once again. However, a stall before breaking through the highs near $42,000 could be positive for the asset, according to Brian Krogsgard, a trader and podcaster known on Twitter as LedgerStatus.

“Bitcoin’s correction has been healthy amid a strong bullish backdrop, moving back toward the 20-day moving average,”

Krogsgard explained to Cointelegraph on Thursday. “After the strong recovery, it’s time to find out if it will continue immediately upward or stay longer in a prolonged consolidation, which in my opinion would be healthy.”

On Thursday, Bitcoin Rush barely broke above $40,000 before retreating slightly, reentering the range around $39,000, TradingView.com data indicated.

Breaking above $36,000 was a major move for the asset, according to comments from CryptoWendyO, a trader and analyst on Twitter. “If we don’t regain the $36,000 I don’t rule out a further collapse,” he told Cointelegraph on Jan. 12, ahead of Bitcoin’s recovery above that level.

New comments from CryptoWendyO express optimism about the price. He recently explained to Cointelegraph:

“Bitcoin has charted a fantastic recovery from my support zone at ~$34,200 after the sharp drop of about 25%. However, I doubt the fundamentals of 2020/2021 will be any different from Bitcoin’s previous history, currently I believe we will continue to rise and I foresee a reversal at $42,000 to mark a similar uptrend to the one following the January 7 correction from ~$34,200 to ~$28,000 to test ~$48,000.”

As for the recent price action, Krogsgard sees a correlation with one of Bitcoin’s products aimed at the mainstream market. “It appears that the closure and reopening of GBTC deposits has had a strong impact on coin demand as the market reopened to a low,” Krogsgard speculated. “I think we will continue to see institutional demand with each contraction.”

Managed by Grayscale, GBTC is essentially Bitcoin in share form, with each share guaranteed by a fraction of a Bitcoin. In December, the company suspended investments in its Bitcoin Trust, reopening them a few days ago.

Here’s how to make huge gains with Bitcoin

The opportunity has not passed you by! Here’s how to make huge gains with Bitcoin

Bitcoin has been making huge gains and hit another all-time high this week. Don’t panic, it’s not too late to get in on the action and there is a way to do so without running the risk of the price falling as fast as it went up.

The strategy we are referring to is crypto arbitrage. It is not something new. It has been around for a while and is growing in popularity not only in the crypto community, but The News Spy also among mainstream investors, as financial institutions, hedge funds, and investment firms of various sizes recognize its value as an exceptionally low risk form of investment, suitable for even the most conservative portfolio.

What makes it so attractive? Not only is the risk close to zero, but it also offers incredible returns.

How does crypto arbitrage compare to other bitcoin investment strategies?

One of the most popular strategies with Bitcoin is short-term trading. The advantage is that you have full control, you can see results within a few hours and the return on investment can be huge. On the other hand, the risks are just as great, and it is equally possible to make a mistake and lose everything as quickly as you gained it. Then, of course, there is the fact that day-to-day trading is a time-consuming and knowledge-intensive activity, involving the need to be glued to your screen using a variety of technical indicators to research price patterns and forecast market movements.

How does crypto arbitrage fare in comparison? Well, firstly, crypto arbitrage is not vulnerable to the volatility of the crypto market, so there is almost no risk, as it generates profits by exploiting price inefficiencies on exchanges.

In other words, for short periods, a cryptocurrency may be available at different prices at the same time. In the short window of time before the market adjusts and the price difference resolves itself, it is possible to buy a coin on a market where the price is lower and then instantly sell it on the market where the price is higher to make a profit on the difference.

Crypto arbitrage tends to be automated as it requires a speed and efficiency that no one person can match. An automated platform does all the work for you, so no knowledge of the market is needed and no effort is required.

To understand this better, let’s take one of the largest regulated crypto arbitrage platforms, ArbiSmart, as an example.

The ArbiSmart platform scans 35 exchanges simultaneously, 24 hours a day. It monitors the market, finding and then exploiting temporary price inefficiencies to generate passive profits of up to 45% per year. Profits are earned on a daily basis and can be withdrawn at any time in fiat or crypto.

HODLing

For those who are comfortable at a more relaxed pace and don’t have the temperament for the high-risk, high-return nature of daily trading, there is always HODLing. This slow but steady approach is very low risk and exceptionally undemanding, as it involves a strategy of doing nothing as you hold your Bitcoins long term until they appreciate over time. Clearly it has worked so far for those traders who entered the market first. However, the downside is that most failed to get into BTC in the early days, so today it is a much more expensive and uncertain strategy. Also, your capital is basically idle and not working for you.

When compared to HODLing, crypto arbitrage is just as undemanding, but has the significant advantage of making you money every minute. In the case of ArbiSmart, for example, you simply register and deposit your Bitcoins or other cryptocurrencies. Your funds are then converted into RBIS, the platform’s native token, to be used for crypto arbitrage trading (they are however withdrawable at any time in fiat or crypto).

Previsione del prezzo di Bitcoin: BTC / USD supera i $ 35.000; il prossimo test potrebbe essere di $ 40.000

Il bitcoin è visto crescere più in alto poiché la criptovaluta viene attualmente scambiata intorno al livello di resistenza di $ 35,012.

BTC / USD è stato in grado di superare i $ 35.000 poiché la moneta viene scambiata al di sopra delle medie mobili di 9 e 21 giorni. Ora, il prossimo obiettivo importante potrebbe essere intorno ai $ 38.000, dove Bitcoin ha solitamente subito una forte resistenza da parte dei venditori. Pertanto, il Bitcoin (BTC) tocca il massimo giornaliero di $ 35.868 all’apertura del mercato oggi e sembra che stia guadagnando una certa stabilità secondo il grafico giornaliero.

BTC supererà il livello di resistenza $ 36.000 o invertirà?

Bitcoin (BTC) viene scambiato a circa $ 35.012 e ha una valutazione di mercato di $ 663 miliardi. Dopo diverse settimane di scambi tra $ 30.000 e $ 34.000, Bitcoin è stato in grado di superare chiaramente i $ 35.000 e raggiungere un prezzo per moneta di $ 35.868. La domanda principale è se sarà in grado di superare $ 38.000 dove di solito può trovare una grande resistenza. Nel frattempo, i trader stanno ora aspettando una continuazione della tendenza rialzista che aiuterebbe Bitcoin a raggiungere nuovi massimi.

Inoltre, per Bitcoin avrebbe raggiunto $ 38.000, questo potrebbe essere l’inizio di una nuova corsa al rialzo nello spazio crittografico. Inoltre, poiché l’RSI (14) sta aumentando vertiginosamente all’interno della regione di ipercomprato, BTC / USD potrebbe presto raggiungere i potenziali livelli di resistenza a $ 38.600, $ 38.800 e $ 39.000 mentre scivolando al di sotto delle medie mobili potrebbe trascinare il prezzo ai livelli di supporto critici di $ 30.700 , $ 30.500 e $ 30.300 rispettivamente.

Tendenza a medio termine BTC / USD: rialzista (grafico a 4 ore)

Guardando il grafico a 4 ore, BTC / USD è visto in ritirata dopo aver toccato il massimo giornaliero a $ 35,868. Il movimento dei prezzi di oggi sembra essere il più impressionante poiché continua a salire al di sopra delle medie mobili con un forte aumento. Tuttavia, BTC / USD sta ora mantenendo la sua corsa al rialzo sopra i 35.400 $ mentre l’RSI (14) si sposta nella regione di ipercomprato.

Happy Holidays – Crypto Twitter celebrates Christmas with a new record high for Bitcoin

Some crypto experts are sending very special Christmas greetings at the new Bitcoin record high.

Crypto Twitter sends exuberant Christmas greetings after Bitcoin ( BTC ) hit another record high

At the time of going to press, the Bitcoin price on Bitstamp had recently hit a high of $ 24,661.76, which further improved the latest record from this week . Altcoins can also gain in the slipstream of the market leader, with Ethereum ( ETH ), Litecoin ( LTC ) and XRP all making significant gains.

Accordingly, crypto influencers and Immediate Edge app advocates celebrated the new record on Twitter, while at the same time advising investors to hold onto their crypto funds. Winklevoss twins Cameron and Tyler, who are best known for their legal dispute with Mark Zuckerberg and are among the most important figures in the industry with their Gemini crypto exchange, write:

While Cameron thanks Santa Claus for giving him a Bitcoin rate of US $ 24,500, Tyler is pleased that there is not the rod this year, but the new record rate.

Morgan Creek Digital co-founder Anthony Pompliano also confirms that the record high will also sweeten his Christmas mood

Mike Novogratz , the head of the crypto investment bank Galaxy Digital, is celebrating with a very special gift. In his tweet, for example, he holds a glowing moon ball in the air, which is supposed to symbolize the meteoric rise of Bitcoin.

Robert Breedlove, the author of the book “Thank God for Bitcoin”, on the other hand, is a little less superficial and reminds his followers of the revolutionary potential of the crypto currency:

“Bitcoin rewards patience and thoughtfulness. Fiat currencies, on the other hand, reward hasty and headless spending in order to get ahead of inflation. What world do you want to live in? In a world in which money is distributed calmly and reasonably or in a world in which it is wasted quickly and senselessly? “

Su Zhu of Three Arrows Capital is again warning the crypto community to HODLn, which means that investors should hold on to their assets in order to take further profits from the crypto market.

Anzahl der Ethereum- und Bitcoin-Nicht-Null-Adressen erreicht neuen Höchstwert

Die Anzahl der Nicht-Null-Adressen sowohl im Ethereum- als auch im Bitcoin-Netzwerk steigt kontinuierlich an.

Beide haben ein Allzeithoch von 50,651M für ETH und 32,925M für Bitcoin erreicht
Diese Aktivität in beiden Netzwerken ist ein klares Zeichen für das Interesse der Investoren und die Akzeptanz der jeweiligen digitalen Vermögenswerte

Der Preisanstieg wird sich sowohl bei Ethereum als auch bei Bitcoin fortsetzen

Die Anzahl der Nicht-Null-Adressen sowohl im Ethereum- als auch im Bitcoin-Netzwerk hat jeweils ein neues Allzeithoch erreicht. Laut den On-Chain-Daten des Teams von Glassnode hat die Anzahl der Nicht-Null-Adressen im Bitcoin-Netzwerk gerade ein neues Allzeithoch von 32.925.521 erreicht. Unten ist ein Diagramm, das mit freundlicher Genehmigung von Glassnode das beeindruckende Wachstum von Bitcoin-Adressen seit 2009 zeigt.

Anzahl der Ethereum- und Bitcoin-Nicht-Null-Adressen erreicht neues ATH 14

Im Fall von Ethereum hat die Anzahl der Nicht-Null-Adressen ein Allzeithoch von 50.656.493 erreicht. Unten ist ein Diagramm ebenfalls von Glassnode, das das Wachstum der Anzahl der Nicht-Null-Adressen im Etheruem-Netzwerk zeigt.

Anzahl der Ethereum- und Bitcoin-Nicht-Null-Adressen erreicht neues ATH 15

Investoreninteresse und Akzeptanz: 2 Gründe, warum die Zahl der BTC- und ETH-Adressen zunimmt

Aus beiden Diagrammen kann man erkennen, dass die Anzahl der Bitcoin- und Ethereum-Adressen dem normalen Verlauf einer S-Adoptionskurve folgt. Aus den Diagrammen kann man auch schließen, dass die Adoption noch nicht die Plateauphase erreicht hat, was bedeutet, dass wir uns noch in der frühen Phase der Kryptoindustrie befinden.

Der erfahrene Bitcoin-Analyst Willy Woo kommentierte kürzlich die Adoption von Bitcoin und wies darauf hin, dass sie schneller wächst als jede andere Technologie-Infrastruktur bis heute.

Die Adoptionskurve von Bitcoin ist schneller als jede andere globale Infrastruktur-Einführung zuvor. Sie wächst schneller als die Einführung des Internets, der Mobiltelefone und leicht schneller als “virtuelle Banking”-Player wie PayPal.

Die Akzeptanz von Ethereum wächst ebenfalls in einem phänomenalen Tempo, wie die obige Grafik und die Wachstumsrate von DeFi zeigt.

Investoren, die das Potenzial von Bitcoin und Ethereum durch die aktuelle Adoptionsrate gesehen haben, sind auch damit beschäftigt, BTC und ETH aufzusammeln, was zu einem Anstieg der Nicht-Null-Adressen in beiden Netzwerken beiträgt.

Wie bei der Adoption ist es noch zu früh, in Bitcoin oder Ethereum zu investieren. Jeder, der in Erwägung zieht, jetzt in Bitcoin und Ethereum zu investieren, sollte eine gewisse Beruhigung darin finden, dass der CEO von Binance, CZ, eine ähnliche Schlussfolgerung im Mai gemacht hat, dass es noch früh im Spiel ist. Seine genauen Worte waren wie folgt.

Jeder, den ich getroffen habe, der in #crypto eingestiegen ist, denkt, dass er zu spät eingestiegen ist, ohne Ausnahme, mich eingeschlossen, bis 5 Jahre später.

Ich erwarte, dass dasselbe im Jahr 2025 der Fall sein wird. Wir sind noch früh im Spiel.

Crypto Weekly # 126 – Cryptocurrency news of the week

News regarding Bitcoin and cryptocurrencies is in constant turmoil. It can happen that important information gets lost in the daily news flow and you miss important points.

This format is there to remedy that. We come back to the news of the past week in the Crypto Weekly to keep you informed on the current situation of cryptocurrencies.

For this week’s unmissable, we’re going to ask ourselves if Bitcoin Bank platform could hit $ 55,000 in 2021? This is what Fanis Michalakis sought to elucidate in his article based on the Stock-to-Flow model.

Le ratio Stock-to-Flow

Let’s first take the time to discuss Stock-to-Flow and what it represents. This ratio , which quite simply corresponds to the division of the existing stock of a good by the quantity of this good newly created each year, is notably introduced by Saifedean Ammous very early in his work “The Bitcoin Standard” , where he addresses the question of money and its forms.

The stock-to-flow , it is understood, is to some extent the scarcity of goods . It expresses how many years it would take, with current production, to double the existing stock of the commodity in question. Gold, for example, with a stock of around 185,000 tonnes and an annual production of 3,000 tonnes, has a Stock-to-Flow of 62 (this data is from the paper published by PlanB).

Stock-to-flow selon PlanB

We know: Bitcoin is not just a “technology” . It is perhaps above all an economic, monetary and social proposition. This proposal is due in particular to the final limited quantity of tokens, since there will never be more than 21 million bitcoins in circulation, with a regular reduction in monetary issuance, which creates a certain notion of scarcity . Hence the idea of ​​bitcoiner PlanB to study the relationship between the scarcity of Bitcoin , measured by its Stock-to-Flow , and its market value .

This is precisely the exercise that PlanB undertook to test its hypothesis. It has indeed collected the data, directly on the blockchain, allowing it to calculate for each month the value of Bitcoin’s Stock-to-Flow since its creation, by going to find, for each period, the number of blocks found (and therefore the number of new bitcoins mined) as well as the quantity of coins in circulation. It then only had to compare the ratio thus calculated with the average price of bitcoin for each month . He thus obtains the following graph with, on the x-axis, the Stock-to-Flow ratioand, on the y-axis, the total market value of bitcoin (i.e. how much are all bitcoins in circulation worth). Note also that the axes are graduated on a logarithmic scale (in other words, there is as much space between 1 and 10 as between 10 and 100, and so on).

Do not hesitate to consult the entire article to know whether or not Bitcoin will wait for $ 55,000: Bitcoin at $ 55,000 in 2021, a math story? The inconstancies of the Stock-to-Flow model

Bitcoin verliert an Schwung bei $19,4K

Market Wrap: Bitcoin verliert an Schwung bei $19,4K; Ethereum-Gebühren steigen

Die Anzahl der Tage mit einem Milliarden-Dollar-Spotvolumen auf dem Bitcoin-Markt nimmt zu und treibt die Preise in die Höhe. Auch die Transaktionsgebühren von Ethereum steigen, da die Nachfrage durch allgemeine Kryptowährungszinsen angeheizt wird.

Bitcoin (BTC) wird ab 21:00 UTC (16:00 Uhr ET) um 18.883 Dollar gehandelt. Rückgang um 0,75% gegenüber den vorangegangenen 24 Stunden.

Bitcoin schloss am Mittwoch bei einem Preis von $19.500 und erreichte laut CoinDesk 20-Daten einen Höchststand von $19.474, bevor es an Schwung verlor und bis zum Redaktionsschluss auf $18.883 fiel.

“Nach einem kometenhaften Anstieg in der vergangenen Woche scheint sich die Bitcoin bei Bitcoin Future bei 19.000 $ konsolidiert zu haben, selbst nachdem sie kurz unter diesen wichtigen psychologischen Meilenstein gefallen war”, bemerkte Guy Hirsch, US-Geschäftsführer für das Multi-Asset-Brokerage eToro. “Dies ist wichtig, weil es zeigt, dass es bei dieser Bewertung zum ersten Mal in seiner Geschichte Unterstützung für Bitcoin gibt.

“Bitcoin hält sich selbst über 19.000 $, so dass wir uns dem Allzeithoch, das wir zuletzt 2017 gesehen haben, um etwa 2% nähern”, bemerkte Elie Le Rest, Partner beim Quantenhandelsunternehmen ExoAlpha. “Jeden Tag sehen wir, dass das Volumen an allen Handelsplätzen zunimmt.

Das Volumen trägt dazu bei, den Preislauf von Bitcoin anzuführen. Tatsächlich ist das kombinierte Tagesvolumen von 1,8 Mrd. USD am Dienstag an den fünf wichtigsten USD/BTC-Spotbörsen (Bitstamp, Coinbase, Gemini, ItBit und Kraken) das zweitgrößte, das im Jahr 2020 verzeichnet wurde, und wurde nur durch das Niveau vom 13. März von 1,9 Mrd. USD übertroffen. Zum Zeitpunkt der Drucklegung näherte sich das Volumen am Mittwoch für die fünf Börsen der 1-Milliarde-Dollar-Grenze.

“In den letzten Wochen haben wir einen aggressiven Anstieg der Volumina erlebt, und wir erwarten nicht, dass dies in den nächsten Tagen zu viel wird”, bemerkte Michael Rabkin, Leiter des institutionellen Vertriebs des Kryptomarktmachers DV Chain. “Aus Preissicht glauben wir, dass dieser risikobehaftete Markt sehr dynamisch ist, und wir können nicht erkennen, dass er in absehbarer Zeit zum Erliegen kommen wird, wenn man bedenkt, wie viel Geld weltweit gedruckt wird.

In der Tat sprang der Geldbestand von M2 in den USA von 15 Billionen Dollar im Januar auf 19 Billionen Dollar im November, ein Anstieg der zirkulierenden Geldmenge um 26%, der in diesem Jahr geschaffen wurde, um die durch den Coronavirus verursachten wirtschaftlichen Probleme abzuwehren.

Und während viele Marktbeobachter über die Nähe von Bitcoin zu einem Allzeit-Preishoch sprechen, ignorieren viele die Auswirkungen, die der Äther ebenfalls auf den Markt hatte. Ein bevorstehendes Upgrade des Netzwerks auf Eth 2.0 plus eine Zunahme der dezentralen Finanzierung, oder DeFi, Anwendungsfälle scheinen das Ätherfeuer zu schüren. Im Jahr 2020 ist die Bitcoin-Menge um über 162% gestiegen, während der Äther um satte 343% zugenommen hat.

“Der jüngste Meilenstein beim Eth 2.0-Vertrag sorgt für eine sehr positive Stimmung rund um den Äther”, bemerkte John Willock, Chief Executive Officer des Krypto-Custody-Anbieters Tritium.

Ether (ETH), die zweitgrößte Kryptowährung nach Marktkapitalisierung, gab am Mittwoch um 581 $ nach und gab in 24 Stunden ab 21:00 UTC (16:00 Uhr ET) um 4,1% nach.

The tax authorities ask them for delusional sums on cryptocurrency gains… non-existent!

Coinbase Makes a Big Blunder – Several US Coinbase users have received mail from the IRS (the US tax authorities) claiming several thousand dollars on cryptocurrency gains. Small problem! Users never realized the affected gains.

127,000 dollars in taxes and penalties for … non-existent winnings

The information was relayed by Cryptotrader.tax, a service specializing in calculating the taxation of cryptocurrencies in the United States.

As an example, John Smith (assumed name to protect user anonymity) received a letter from the IRS (Internal Revenue Service) notifying him that he had under-reported his income in 2018 “Due to the failure to include its cryptocurrency investment activity” . In total, he would be asked to pay some $ 120,960 in taxes and penalties.

Mail received by the user – Source: Cryptotrader

Yet it would appear that this claim is totally unfounded. As Cryptotrader points out, it was actually the IRS that owed Smith money, as he had suffered $ 2,000 in cryptocurrency losses that year.

The case of John Smith is not isolated, because in the space of 2 days, Bitcoin Bonanza was contacted by dozens of Internet users who received similar emails.

Whose fault is it ?

Also according to Cryptotarder, it seems that exchange platforms , such as Coinbase , are at the origin of this misunderstanding of several hundred thousand dollars .

In fact, these exchange platforms would communicate information about their users via form 1099-K instead of using 1099 or 1099-B, which would be appropriate for their business.

“The 1099-K was never intended as a tax return form for cryptocurrency exchanges. It was designed to report income from platforms where you get paid directly by third-party merchants, like Uber, Lyft, and Etsy. The form does not make sense in the context of cryptocurrency exchanges. And yet, many large exchanges, like Coinbase, have decided to use Form 1099 to report customer income information. “

Quão vulneráveis são os contratos inteligentes do Ethereum?

Quão vulneráveis são os contratos inteligentes do Ethereum?

Com o valor total dos ativos trancados na DeFi agora valendo mais de 13 bilhões de dólares, muitos esperam que esta parte do cripto-espaço cresça a um ritmo rápido. De fato, somente no terceiro trimestre de 2020, o ecossistema DeFi viu seu volume de transações ultrapassar US$123 bilhões, com 96% do total pertencente ao Ethereum. No entanto, o crescimento da DeFi sofreu no passado Bitcoin Billionaire com a escalabilidade do Ethereum e com as altas taxas de gás. Agora parece que as falhas da rede não terminam aqui.

Uma investigação recente dos contratos inteligentes do Ethereum descobriu que quase 3.800 contratos inteligentes tinham “fraquezas graves” que poderiam permitir que cibercriminosos roubassem rapidamente um milhão de dólares. Os pesquisadores em questão foram capazes de examinar seis meses de bloqueios da cadeia de bloqueio do Ethereum e descobriram que 3.779 contratos tinham 13 tipos diferentes de vulnerabilidades, incluindo 4 vulnerabilidades de alta variação. O valor total desses contratos inteligentes vulneráveis era de 2.088 ETH, o que equivale a 964.172 dólares, que a equipe encontrou.

Entretanto, o espaço em questão não é novidade para tais vulnerabilidades e falhas relacionadas

Na verdade, em 2016, uma vulnerabilidade de contrato inteligente Ethereum conhecida como “ataque de reentrância” permitiu que um criminoso cibernético roubasse 50 milhões de dólares.

Nesse caso, os pesquisadores descobriram que o ataque de reentrância afetou a forma como as fichas DAO do fundo de capital de risco descentralizado eram negociadas. Devido a uma falha no código do contrato inteligente, um atacante foi capaz de retirar fundos continuamente em um loop quase infinito. De fato, mesmo os protocolos Uniswap e Lendf.me enfrentaram ataques de reentrância no passado, com cada um destes ataques alimentando mais perguntas sobre a segurança e proteção da DeFi.

Enquanto o Ethereum continua sendo um dos gigantes do cripto-espaço com mais de 1.900 fichas diferentes construídas em cima dele, para que a DeFi se torne mainstream, os desenvolvedores precisam primeiro proteger sua arquitetura. As etapas podem incluir mais auditoria, verificação mais rigorosa dos contratos inteligentes, e até mesmo a implementação de programas de recompensa de bugs para capturar vulnerabilidades.

No que diz respeito aos usuários, os pesquisadores em questão recomendaram que eles verificassem se as plataformas em que eles estão utilizando um contrato inteligente com vulnerabilidades. Por exemplo, os usuários podem fazer uso do Etherscan ou de um explorador similar para ver se estes contratos foram auditados e verificados.
