Ethereum Miners Are Selling Their Graphics Cards

This writer suspects that the Ethereum craze may be slowing down, at least a little bit, based on the rapidly increasing sales of used mining rigs on eBay. While sellers could simply be moving more mining rigs to meet demand, being that interest in Ethereum remains high, those who were queried claim that they are, in fact, getting out of the market. Of course, nobody knows for sure when the exorbitant markups on certain GPUs will officially end. ...ethereum mining gets more difficult over time, causing any particular hardware setup to gradually earn less money every day. Based on the RX580's processing ability, power consumption, the drop in trading price, and the increase in mining difficulty, I did some back-of-the-envelope calculations. According to my math, the same graphics card that used to earn about $5 a day now earns less than roughly $2 a day. A $300 graphics card that might have paid for itself in 2-3 months (after electricity costs) will now take over 6 months, at best. A sizable mining operation can stomach that sort of long-term investment, but there aren't a lot of hobbyists who are willing to stick it out.
