I got the lifetime contracts with Hashing 24 back when they had them and they just sent me the same message. I've also got two S9's on timers that turn off during peak electricity and have to shut them down, and I have lowest electricity cost in the US. The trading bots are making more than the miners now. I hope you get into bot trading because we need to figure out the best settings. They are not arbitrage trading, API keys on the exchange don't let you withdraw, they are just placing an opposite order once one executes. I've had sell-buy-sells execute in minutes. Get a mini PC and leave that thing running 24/7 on BTC/alt coin markets. Don't get stuck holding tether.
