I need advice on staking

Dear all

I am fairly new to the crypto world and just started to learn about the concept of staking. I wanted to give it a shot but I was hoping you could give me some advice on a few things.

I have a „ ledger „wallet and noticed it offers staking for a variety of currencies. So this seems comfortable as I don’t have to switch to a new app or wallet. The rate starts at 3.1% for ETH all the way up to 10%+ …. I’d appreciate your feedback on the following questions:

Which platforms do you use and which currencies?

What is your average return on investment?

What are the biggest risks when I stake?

What should I avoid at all costs?

Thank you so much
