I read about many so called Bitcoin Banks, Projects, who promise you 3% interest annually, simply don't believe in holding your bitcoins in one place for such a long time.
First of all, sorry to hear that you lost all that crypto this year. Obviously you picked the wrong investments, which is really easy to do these days.
You seem to want guaranteed income on a crypto investment, but I've learned over the years that there is no such thing and anybody promising that is likely to be a scammer. To date there haven't been any so called crypto banks offering fixed interest rates on deposits like you would find in a real life bank using fiat currency. Don't expect to find one anytime soon.
My suggestion is to convert whatever altcoins/tokens you have into bitcoin and just hodl on tight. Bitcoin is going to rebound in the market and will eventually climb higher than it's ever been before. I would not try to increase your holdings by actively trading/lending/whatever, because all of that is more risk than you probably want.
