why bitcoin mining difficulty is increased?
I just want to knows that why the bitcoin mining difficulty level is increased and i am afraid of the life of future miners.Maybe in future the miners electricity will cost more than our rewards because of the difficulty level.
When number of users mining on one coin increases, the difficulties increase. I could see, day by day the mining platform is expended and the difficulties increases. We can better skip mining from one coin to other depending upon the availability and profits. I do mine BTC, ZCASH, ETH and DASH from CPU. I switch over from one to the other coin. Receive enough profits.
Do we have any other ways to reduce this difficulties. I would be happy to hear from my folks here.
