Will virtual currency be finished
I hope I can help you. Thank you for your adoption.

it is estimated that 21 million pieces will be excavated in 2140

according to the relevant literature of bitcoin, in 2140, 2100 bitcoins will be proced and will not grow any more. According to the principle of bitcoin, after 33 halving periods, the mining output of each block will reach 0.58 Cong, less than the minimum unit of one Cong. The interval of each half rection is 210000 blocks, and the total proction time (2140 years) given in the above literature is calculated from the proction time of each block of 10 minutes 210000 * 10 / 60 / 24 / 365 = 3.9954 * 33 = 132 years. Since 2008, 132 years later, it is 2140 years)
however, the "proction time of each block is 10 minutes" used in the above calculation method is an ideal state, which is only true when the computing power and difficulty of the whole network do not change. Looking at the bitcoin blockchain, it is not difficult to find that bitcoin's whole network computing power has been growing for a long time, and the difficulty of mining has also increased. Therefore, it is not difficult to find out that the above calculation is not tenable and there is a huge error
the shortcomings of the above methods are that they can not accurately predict the change of bitcoin network computing power and the mining speed of bitcoin. The 11.3-day data used in the above calculation method is only the average value from May 2013 to April 5, 2014, and the representativeness is questionable. We can integrate the results of big data analysis and mining machine proction to establish a more accurate mathematical model
17 million bitcoins will be mined in the next few days. According to the design of the founder of bitcoin, Nakamoto Tsung, the mining limit of the virtual currency is about 21 million, which means that global miners will compete for the remaining 4 million bitcoins
after breaking through the $10000 mark in early March, bitcoin fell all the way to around $6000. By the end of this day, bitcoin was close to the $10000 valuation again and had risen to $9800 in some bitcoin exchanges.
every 10 minutes, the miners of the whole network work together to solve a problem and compete for bookkeeping rights and bitcoin rewards. If the computing power of the whole network continues to grow, bitcoin will soon be g out
in order to ensure the stability of bitcoin and dig out a block in about 10 minutes, Nakamoto Tsung designed that the difficulty of getting bitcoin from miners' mining should be dynamically adjusted every 2016 blocks (about 2 weeks). After the adjustment, the expected time for each block to be generated is 10 minutes
the current difficulty coefficient is about 480ph / s, which is about 68 billion times that of Genesis block. In other words, with the current computing power, the miners in the whole network need to go through about 300 trillion hash operations to find a qualified answer and generate a new block.
