I am getting more and more interested in the topic of cryptocurrency wallets especially on the background of what I read in the article from https://dhanleelainvestments.com/2022/05/25/what-is-a-fiat-wallet/. I never thought before that holding money on exchange I actually don't own it, because in crypto there is such an expression "not your money". So now I'm looking for what kind of cold wallet to buy. Can anyone advise something?
