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.
In my opinion, digging BTC is a difficult and tedious task. I would never do it despite the experience I had. I prefer to hold more coins and wait until they multiply themselves. Let's leave for good and experienced diggers.
