Bitcoin broke for the third time
there are basically two kinds of attacks, one is dictionary attack, the other is brute force attack
dictionary attack is to use common passwords and their simple variants as keys one by one. As long as your pass phrase is not hard enough, the possibility of successful attack is very high. So if you want to use this, you need to popularize the knowledge of cryptography first, and don't think it's very safe to add a long password
if you don't use the wallet generated by pass phrase, you can only crack it violently, which is equivalent to enumerating all the possible keys. At present, this is impossible, even if the electronic computer is becoming more and more powerful. However, quantum computer can do it theoretically, but don't worry too much. If such a powerful quantum computer comes out, it will not only endanger bitcoin
at the same time, bitcoin has a second layer of protection: if an address only accepts bitcoin but does not output it, its public key is confidential, that is to say, no one else can see the box, only the box number. At present, the process of decing the box from the box number can't even be done by quantum computer. In other words, if there is a quantum computer, bitcoin has a last line of Defense: it's temporarily safe to transfer your money to a new address
finally, some time ago, the wallet generated by the Android client was attacked because of a bug in the underlying random number generator. In fact, this function is not random securerandom, which Google quickly admitted and fixed. It's hard to say whether this kind of thing will happen again, but I don't think we need to worry too much.
After entering 2021, bitcoin has always attracted the attention of the market, because the soaring trend of bitcoin is quite amazing. According to the data, bitcoin rose above $48000, the highest level ever. With the optimism and doubts of investors and the scrutiny and warning of regulators, bitcoin started from US $963.66 at the beginning of the year and broke through the important barrier of US $10000 in many trading platforms around the world. Such a surge is not only faster than expected by the market, but also unexpected by regulators. The driving force and causal logic behind it are worth pondering
unlike legal tender in reality, which has unlimited supply (as long as the economy permits and human needs), bitcoin has locked the upper limit of quantity from the beginning. According to the design of the founder of bitcoin, Nakamoto Tsung, 10.5 million bitcoins can be g up in the first four years, and then halved every four years. After 2030, only 1 million bitcoins will be left. Until 2140, when the last one is g up, the total number of bitcoins will reach 21 million, which is also the largest supply of bitcoins. The crux of the problem is that bitcoin is actually much less used for online transactions. According to the Research Report of chainalysis, a digital forensics company, about 2.78 million to 3.79 million bitcoins have disappeared forever, equivalent to 17% to 23% of the total number of bitcoins. This is mainly e to some early & lt; Miner & quot; If you forget your bitcoin wallet account e to computer obsolescence and other reasons, these bitcoins will always be in & lt; Deep sleep & quot; Status. In this way, the value of collecting bitcoin is self-evident, and things are rare and precious; Scarcity & quot; As the price is rising, bitcoin shows the basic characteristics of commodity currencies such as gold and silver
bitcoin has become one of the hottest topics at present. however, if we simply regard bitcoin's breakthrough of $30000 as a fraud, then some of them are relatively simple. After all, bitcoin is still of great value as the most valuable virtual currency. The blockchain behind it also represents another development direction. In fact, netizens have had a lot of discussions on this. I have also given other answers to such questions. If you like, you can have a look{ Third, how to look at the future development of bitcoin
in my opinion, after this soaring, bitcoin may usher in a slump in the future. So I hope you can look at such an event rationally. And for those who invest in bitcoin, they also hope that they can treat it rationally. After all, the price of bitcoin has reached the point that ordinary people can't accept. Most importantly, I hope you can understand that we have never acknowledged bitcoin from the beginning to the end
because the vast majority of people believe that bitcoin can proce greater value in the future, and institutions and investors all over the world are optimistic, it can be pursued by a wide range of people. In fact, this is also the essence of speculation. Only more people believe that bitcoin can obtain profits can it be pursued by people
the price of bitcoin has exceeded US $56000, which is unthinkable to ordinary people, because ordinary people do not have any money to save to buy bitcoin. In fact, the current social atmosphere is not good at all. Apart from speculation, there is no better way to let assets appreciate. Speculation can not last long, So sooner or later there will be a problem P> first, there will be bubbles in hyped procts. P> in this society, in fact, for any scarce procts, it can be hyped, but in the process of speculation, the final result will be a bubble. Once the bubble burst, will surely cause more people to generate capital losses, and more people will lose their fortune. So ordinary people simply can't afford to play such a game, and they are not qualified to play such a game. They must control and reflect on their own behavior{ RRRRR}
in fact, the price of bitcoin has changed a lot in the past ten years. It has changed millions of times, which is impossible for any asset to achieve such a rise. even Alibaba and Tencent can not have such a rise, so the price of bitcoin has changed so much, it will certainly be sought after by the society, because more people believe that bitcoin can generate more funds, so they will pursue it. In fact, this is human greed
's bitcoin is rising crazily just because central banks are constantly letting money out of the water. Once liquidity is tight, the bubble will burst. according to media reports, good news is coming from the bitcoin market again. In the latest trading day, the price of bitcoin has exceeded US $58000, a new high in recent years. At the same time, in the trading day when bitcoin soared, 140000 bitcoin investors burst their positions, accumulating more than US $1.1 billion. The bitcoin market once again suffered a double day of ice and fire. Optimistic investors continue to increase their positions and bet that the price of bitcoin will soar. On the other hand, many investors have lost their money because of shorting bitcoin
bitcoin fell below $37000, in sharp contrast to the previous surge bitcoin, a peer-to-peer payment system, was launched on January 3, 2009. Its founder is little known because all the original discussions about currency and agreements were published by Nakamoto's people
to sum up, although bitcoin futures contracts launched on the platform are more professional and standardized in contract design and risk control system than those launched on private platforms, , they are still faced with the risk of large price fluctuation and easy manipulation in the spot market. In the final analysis, this is because bitcoin, as a private digital currency, lacks value orientation and regulatory constraints strong>
