The problem is that miner asics are more than expensive at the moment, and that is the main reason of why only a FEW people can buy them to mine, also, there are some people that are mining in places in where electricity is more than expensive
Even if expensive, there are still chancee that they will make it in the long run. So I guess they are just mining and storing up bitcoin for the better days when the price of bitcoin will moon again. The only problem we might be experiencing in the bitcoin mining is the cost of electricity which can be really very high. This the more reason why most people are shifting into solar as the source if their electricity.
