This shit has all happened before... a few times over. Bitcoin, then Litecoin, then ETH and more recently a huge bubble and hundreds of shitcoins.

I started mining ETH more than 2 years ago and when I started I was making 5 ETH every 2 or 3 days. I once had nearly 200 ETH. I sold most of it when ETH got to $50 thinking about the times when I saw it down between $8 and $15. Obviously I should have HODL but hindsight is 20/20.

The only thing you can do in times like this if you have GPUs is to find a coin/project you really believe in - meaning do lots of research until you understand what it is trying to achieve and understand it, and then mine it and HODL. Choose 2 or 3 of these and don't dump them unless you are sure.

You might get lucky but you probably won't. Don't be like me and sell something at a 20th of its ultimate value! HODL!

Right now I mine mostly Loki. I think it has potential and it has a great dev team. I also sometimes still mine ETH because although the difficulty is ridiculous and reward tiny - it is still one of the most ambitious blockchain projects ever realized and underpins hundreds of other projects. Most of them are scams or vapourware but maybe 2 or 3 of them will one day actually do something that will be "mainstream". Then ETH will be worth more than BTC.
