at present, the computing power of bitcoin in the whole network has reached 2.36 billion hash collisions per second, which is equivalent to the number of water droplets in more than 200000 50 meter long standard swimming pools. But even with such a large amount of computing power, it will take about 10 minutes to hit a hash value that meets the requirements
in 2012, bitcoin's output was halved for the first time, and in July 2016, bitcoin's output was halved for the second time. At present, 12.5 bitcoins are awarded for recording one page of account book. The next halving will take place around 2020, and the total number of bitcoins will not increase by 2040, with a total of 21 million. In other words, the difficulty of digging bitcoin is increasing, while the time required is increasing
Recently, the award-winning sentiment of the winners of a company's annual meeting spread in the circle of wechat friends: "first of all, I sincerely thank the company for rewarding me with 10 bitcoins worth 630000 yuan, and I feel lucky that I can win the prize worth 590000 yuan. Next, I'm going to make a good plan on how to use the 570000 yuan, after all, 550000 yuan is not a small amount...". Although it's just a joke, the price of bitcoin has been falling as it said
some analysts also believe that the trading price of bitcoin once fell below US $6000 before the chairman of the Commodity Futures Commission (CFTC) and the securities and Futures Commission (SEC), the two major US regulators, testified in the Senate on February 6 because of concerns about the US government's strict supervision. According to the testimony of CFTC and SEC presidents, they believe that Congress should consider expanding the scope of supervision of cryptocurrencies such as bitcoin, because most of these assets are not subject to investor protection laws
the current international pyramid schemes are all engaged in this. Bitcoin is not pyramid schemes, but the people's Bank of China has already defined bitcoin. Other pyramid schemes like virtual money are mostly about what they can sell even if they can make a fortune.
the assumption is that six data blocks can be generated every hour in the world, and 210000 data blocks can be generated every four years; Then it makes a decreasing payment for the return of data blocks, 50 bitcoin for each data block in the first four years, 25 bitcoin for each data block in the second four years, 12.5 bitcoin for each data block in the third four years, and so on... Finally, the total number of bitcoins is -
210000 x (50 + 25 + 12.5 + 6.25 + 3.125 +...) = 21 million
the cumulative sum in brackets is close to 100 and will never exceed 100, so the total number of bitcoins is 21 million
currently in the second four-year period, each calculated data block contains 25 bitcoins
2. There is no loss of wealth. Many people at home and abroad are digging for bitcoin, and they are also speculating in bitcoin. Computer and Internet speed can only determine the speed of bitcoin digging, but not the value of bitcoin. Even if you say that we dig abroad, we fry. Now we buy a bitcoin for $300, and there will be no bitcoin to dig in the future. Maybe a bitcoin will sell for $3000, and then we sell it again, won't we make a profit? Where is the loss of wealth? Of course, maybe a bitcoin will be worth $3 at that time. Who can say that it is not born by the central banks
3. In addition to bitcoin, there are several similar virtual currencies such as lightcoin. However, they all adopt similar design principles. Therefore, in the future, there will inevitably be a problem that the currency will eventually be widely recognized, and other currencies that are not recognized will be eliminated. Otherwise, a new virtual currency can pop up at any time. It's not the same as printing money, which completely goes against their original design intention.
