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.
Mining is very expensive now. Miners spend more on electricity than do bitcoins. And in the future it will be even more expensive. If the bitcoin price stabilizes, and enough miners come to this market, in the near future, you can expect a fivefold increase in their energy consumption.
