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.
Yeah for now bitcoin mining would not be that good because of the current market price for bitcoin which is down. So probably bitcoin mining establishment for now would take lesser bitcoins in the process because of the market current situation. Anyway if bitcoin will go strong again then it would be good for mining bitcoin also.
