Can bitcoin be destroyed
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.
According to the data of okcoin, a well-known digital asset trading platform in China, yesterday (June 14), most of the trading hours of the currency price showed a narrow consolidation operation. The amplitude was less than 4% from the opening to 20 o'clock in the evening, and then there was a big drop, reaching the lowest of 18136 at the close. As of today's press release, currency price inertia fell to the lowest 17425 line, the latest trading at 17800
According to analysts of okcoin bank, the daily line level, yesterday's daily line closed the spindle line with short upper and lower shadow lines, and the 5-day moving average crossed the 10 day moving average to form a high dead cross. The trading volume continued to shrink and the trend of this level weakened; At the 4-hour level, the moving average system (5, 10, 20) formed a downward divergent pattern of short positions after being glued, and MACD index continued to operate in the weak area below the zero axis; 1 hour level, short trend is also good, temporarily deviated from the bottom of the volume and price, short-term rebound or finishing demandto sum up, the current major cycles, including the daily line, have entered the short-term operation pattern, and the probability of effective stop fall reversal is very small, so don't rush into the market to buy the bottom. In view of the current market, we can only take short-term strategy and intervene in batches at important (important) support levels. Focus on the support range of 15600-16000 within the day. If the price stops falling in this area, you can build a position to intervene. The upper pressure focuses on the platform low of 17800, and rebounds to this position. The nearby area will leave and wait. Personal suggestions, for reference only
