Hi Nanzo
I agree that the best place for my coins is in my cold wallet. Exchanges can serve the purpose of giving access to coins I want to invest in, but otherwise they are a huge central point of failure. They remind me of a saying a famous bank robber made when he was captured. The authorities said “why do you rob banks” he replied “ because that’s where the money is”. I think the web page based exchanges are a huge target and a challenge to hackers and scammers, and the prize for s successful hack is so large it’s irresistable. So the less time my money spends there the better. 🤣😂😀
