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.
It's part of the parameter. Bitcoin mining might stop being profitable in some years or it's price might increase high enough. So far it's a matter of mystery, the only thing we can do is keep up with the news, analyze the information that comes up and hopefully in the future being able to see it coming before it happens.
