One thing to say mining bitcoin consumes a large amount of electricity and it would take lots of equipment to manned the mining. There should be a development in making the cost of bitcoin lower; given that lower mining cost could yield a higher profit. However, it matters on trading and exchanges.
For me i did not in favor in bitcoin mining because the mining rig is very expensive aside from costly electricity and the amount of coins mine is not good enough to pay mining expenses so i prefer to buy a crypto investment and i can easily without any stress.
