Still, if you do not own the private keys, you own nothing.

That is a fact, hard one! I think i need hardware wallet in my life.

My brother @autofreak, thank you very much, you have said it all, and yes! what are you waiting for brother? go get a hardware wallet, ASAP! I agree @aljustun tokens do not have private keys, but the ethereum wallet you put them in has one, or do you mean there are actual coins out there without a private key? I really doubt that, as it defeats the purpose of why it's a cryptocurrency in the first place. There must be a form of something private only you should have access to like private keys, seed keys, mnemonic phrases etc
