Where can I stake my ETH with some security? You usually have to leave them on a platform and lose the keys - not your keys = not your coins
Staking etherium is available on centralized and decentralized platforms. It is much more convenient to do it on centralized platforms, but the rule “not your keys = not your coins” works here.
There is a lot of information on decentralized platforms and steaking options on the internet, so I won't give links.
I've been telling everyone for years: possible profit 5%, possible loss 100% of deposit - it's a wrong investment if you don't have a lot of coins.
Yeah, everybody's choice, of course, but everybody would choose stability and security over the potential profit at hand, in my opinion.
