Why has bitcoin been falling
according to foreign media reports, on Monday, the price of bitcoin fell to $2526.4, with a maximum decline of 14.5%, which created the biggest decline since January 2015. A few days ago, the price of bitcoin just broke the $3000 mark, a new record, but then plummeted by more than 30%. As of the 16th of this week, the market value of bitcoin has evaporated $10 billion, almost equal to the market value of social software Twitter's $12 billion
the other reasons for the sharp decline include the sharp decline of US technology stocks and the poor outlook of investment banks on the special currency. Morgan Stanley said that "the virtual currency is like the currency of the wild west", which needs to be regulated before it can continue to rise. The previous price surge may be caused by speculation and not easy to sell
it is worth mentioning that bitcoin is not the only one that has plummeted. It is said that the prices of other digital currencies have also fallen considerably

the issuance of bitcoin does not depend on indivials or teams, but through a process called "mining". By solving the problem of cryptography, people get the right to create new blocks and get rewards. It can be said that the new bitcoin is proced to reward miners to verify blocks. In the beginning, 50 bitcoins were awarded for each block packed. Nakamoto designed a set of rules. For every 210000 blocks excavated (about four years), the reward will be halved. This is what we call "halving" event
the first half was at the end of 2012, when 50 bitcoins were awarded to the 210000 block, but only 25 bitcoins were awarded to the 210001 block
the second half took place in the middle of 2016, and the reward was halved again, so 12.5 bitcoins were awarded in 420001 block
and so on...
until around 2140, 21 million bitcoins were g up, and then they stopped rewarding
Why do we need this half design? If bitcoin is issued too fast and there is no circulation limit, there will be a large amount of bitcoin in circulation in the market, and it will definitely be greatly devalued. One thing to remember: bitcoin is valuable. First, the number of bitcoins is fixed, that is 21 million; Moreover, through the halving process, inflation in the bitcoin economy can be suppressed
the third halving will take place in May this year. Let's wait and see.
in addition, the underlying reason is that the world does not recognize the monetary payment property of bitcoin, but regards it as an investment commodity similar to gold, and even has large-scale capital participation in speculation.
in fact, the essence of special currency is a lot of special solutions generated by a lot of complex algorithms. The system will choose a correct answer every ten minutes. Whoever can find the correct answer in the first ten minutes will get a reward. The upper limit of bitcoin is 21 million. When bitcoin was born in 2009, each reward was 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the bounty will be halved to 25. When the total amount reaches 15.75 million (5.25 million new output, or 50% of 1050), the bounty will be further halved to 12.5, and so on. Therefore, bitcoin circulating in this mode can not be recovered to zero, because everyone is the issuer of bitcoin. Unless everyone clears their account number and no longer digs, bitcoin will always be active
