You can do pools with less, like 4 ETH on https://rocketpool.net/For example i read that i need 32 eth to start staking xD
I really like cosmos chains. You can see a list of them here: https://cosmos.network/ecosystem/apps These do not have minimum required to stake or it's really low. Of course there is staking outside of these 2 ecosystems. Search more on coingeckoCan you preferre some, where i can start ?
You receive a small amount all the time that adds up to the promised amount yearly.For example, if I stake 4 ETH, do I have an annual return of about 3% or what does that look like?
Is it the same return for altcoins, cosmochains?
So you think staking is better? But then you need an amount of coins already.
