IMHO, the market is going to go back up within the next few months, however, before things get better, they're going to get worse. Also, you could try shorting your investments, you can check out a tutorial here: https://www.youtube.com/watch?v=4I61bOOryqQ&t=592s

I would probably short Ethereum, and have tried shorting other coins, and probably buy back once we see a bull market. If anyone is looking on how to short I found a tutorial on youtube:

I think some cryptos do have a future, the problem is that there are some things that may not make sense if they are decentralized. Such as if Uber or Airbnb were decentralized, would we get the same level of support? If we look at the money making perspective, we can short coins to save them (however risky)
