In Q3 2018 market is still a blood bath. A lot of people that involved in crypto losing theirs hopes on a quick moon. ICO market is down. But difficulty of mining is growing up. We need more powerful processors, GPU and so on. Mining was created to give ordinary people get some free coins. Another hand big companies joint into monster to dig more digital gold. Simple person is out of this business. To support a node of ethereum you need more space every month and you get no reward. Do you think its fair enough or we need some new architecture to give mining a new life?
No, i think mining is not too profitable anymore unless your electricity is free or you can get free rigs.
But you may wonder why peoples still mining crypto ? I guess the answer is because they want to accumulating and storing the coins, not selling it yet.
Waiting for the market to recover, and they can sell it later, just consider it is as a savings for now.
