Thanks everybody for the inputs. I already hold around 10% of my assets in bitcoin and will grow that over time. I was just looking for an alternative to deploy the rest on something that would give me a steady stream of passive income without much volatility. I know jack 0 about stocks and deposits in FIAT are a laugung matter...so these stablecoin deposits with 8-12% APY look good at a first glance (APY over inflation, guaranteed passive income, bla bla bla).
I just don't want to loose it all putting it in some kind of a scam altcoin. Disclaimer: I already deployed some in USDC and EURS in youhodler (mostly EURS as the EURO is what we use) and no issues so far. I am just not that confident in deploying more, when I know next to nothing about the reliability and endurance of these projects.
