How long is the life of the machine
generally, the service life of mining machines is the whole network, and the relationship between computing power growth is the biggest, because the updating speed of mining machines is amazing. If you can't keep up with the cutting edge of the times, it's very difficult to make profits by using the old mining machines. Naturally, this kind of mining machine will be eliminated, short days, long months, but the general mining machines are rarely used for a year
of course, if the quality of the miner is OK, it will be OK to use it for one or two years
if your electricity price is low or free, then your mining machine will have a long service life, because a large amount of mining consumption is electricity
of course, it is only related to the price of currency. If the price of currency is high and profitable, the life of mining machinery will be delayed, and if the price of currency remains low, the mining machinery will be eliminated quickly.

how many years can the ether coin be g
how many Ethernet coins can be proced each year? At present, five new ether coins are generated for each new block. If you dig out a block every 14 seconds, it will take 31.5 million seconds (365 x 24 x 60 x 60) a year, which means that 2.25 million blocks are g out every year
every miner has considered how long the ether coin can be g, whether I can't dig the ether coin after I buy the miner, or I can't dig the ether coin after I invest in the miner. I can tell you clearly that the ether coin can't be g up, and the official shows the quantity when it comes to the ether coin, but don't go, Ethernet currency is constantly bifurcating. Once the quantity is threatened, it will continue to bifurcate. The miners can continue to dig for new currencies from the bifurcations. For example, etc and ETF are examples. After the bifurcations, the ETH price will go up crazily. Therefore, miners need not worry about the quantity of Ethernet currency.
