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.
That is true only if we are trying to mine ony by ourselfes. If we are trying to make something with some people it could be easier and it could lead to profits after some time of mining.
