What should I do?

I have 2 ETH just sat in a exchange (Kraken) mainly because Binance was getting kicked out of the UK at the time so I moved it there. Now I am wondering what I should do? I only realised I had it after I thought about NFTs (not expensive ones, I wanted a Star Wars trading card 😅 £3) then I needed my master key…. Blah blah blah, eventually I signed up to crypto.(com) to withdraw to my wallet, but now I need to wait another day.

Anyway On this new exchange there is staking and it says expected 30% return? That seems very good, after 90 days that would mean I almost have 2.6ETH? But also I’ve heard of cold storage, I don’t need access to the funds so anything is on the table. They have probably been sat still for around 5 months now.

Anything else you think I should do/look into. Or should I do 1 of the thing listed? And if so is crypto.(com) a good place to do that?

Thanks.
