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.
I do not think it is expensive. Although it uses a lot of power to dig up coin, the value it gives is very high when Bitcoin is at $ 7k3.I feel this is a promising mining industry. Although the number of coin has increased to 17 million, there are still plenty of opportunities for us to get rich. I am intending to import Bitcoin diggers.
