I have recently started to be interested in the issue of cryptocurrency, please, tell me which exchanges are considered the safest and most convenient?
Based on my personal experience I would say Binance and Kraken but I also like KuCoin when I need to buy some altcoin that is not yet on Binance. A long time ago I used Bitstamp, never had any problem, I know they're still around so I guess they're solid. Anyway remember that you're supposed to buy and move your funds out of the exchange, don't use it as a wallet, it's called exchange for a reason.
