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?
For some peoples, mining is still generating fair profit for them. They would not mining if they didn't get any profit from it.
Although some miners are retired from mining because the price so bad in the market, not all miners retired from mining.
Some may still mining but not selling their coins.
