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
so far, the number of bitcoins has reached 12 million. To be exact, the maximum number of bitcoins should be 2099990000, but in fact, the current mining (mining) process is quite difficult - no less difficult than connecting 1000 home computers, and then continuously calculating for a month, it is not possible to dig out a bitcoin
I hope I can help you.
in addition, the income from mining is not completely proportional to the output of mining, and the income from mining needs to consider a variety of factors

in the figure, the cyan line is the price, and the purple line is the 200 day fixed investment cost
most of the time, the cyan line is above the purple line
long term regular purchase, and the average cost is below the current price most of the time. The average cost of buying bitcoin may or may not decrease, because the price of bitcoin continues to rise
