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.
Bitcoin mining is not like just farming. It takes a limited amount of coins from a limited source. There are more and more miners increasing day by day and this is making mining difficult and costly too. If we have to solve this one need to increase the amount of total BTC in the world or one day there will be no miners left around the world as the cost of electricty will exceed the profit.
