I think the dam is springing leaks fast --- and I predict that within 3 weeks you'll no longer be able to sell a used GPU for more than new MSRP. I base this OPINION on these factors in Crypto. In order of decreasing concern: A) Crypto value dropping due to too many factors to list, but a big one is tax implications around the world (not just IRS) - many countries are spinning up regulation, and tax review. Another concern (that the new green money is learning the hard way) is unregulated market manipulation (pump and dump) leads to completely unpredictable volatility, and that quickly leads from feelings of optimism --- to hey!!! unfair advantage!!! to the new bloods. B) Volta/Ampere release lingers JUST outside the viewable horizon, but anticipation is absolutely immense. Potentially 50-70% increased hashrate with GDDR6 at 30% less power rumors are exciting! Also Bitmain seems almost unstable at this point releasing new miners at a ever increasing rate - tackling the current most profitable coins every couple months. C) Ease of accessibility of crypto mining with tools like NiceHash, Minergate, Winminer, Awesome Miner, EthOS, SMOS, etc has lead to difficulty spiking as an increasing number of new hobbyist get into mining. (I'm not saying this is a bad thing -- you need new people to make crypto grow!!! -- but it does/can lead to increased difficulty mining) D) Electricity price spikes in the next couple months for the Northern Hemisphere (Electricity doubles in cost in May for many of us - and that's a shadow in everyone's mind - as is mining heat against A/C usage/cooling of our homes). I.E. Do I hold through this low point, or do I sell in anticipation of no profit at all when my electricity price doubles in May. E) General pessimistic views in the news cycles on Crypto from every angle. In November/December of last year there was a lot of optimistic stories, now it seems the majority are negative. F) Bitmain Eth ASIC rumors -- displacement of GPU miners targeting ETH means increased difficulty for other alt-coins, and less profitability for existing miners --- leading ultimately to used GPU market flooding.
