Im quite new to crypto so i wanted to know what exchanges do you use and i'd be grateful for advises on security. I currently keep my crypto on localbitcoins but it recently got hacked to im concerned for my money. I want to move it somewhere safe but still be able to make trades without much fuss. Im still learning to trade but im pretty serious about it. Can you recommend me a good exchange that hasn't been hacked yet?
Keeping your coins in exchanges is the worst thing to do. You never know when these exchanges go down. It has occurred quite frequently, starting with Mt Gox in 2014, to the recent hacks of Bitfinex and Cryptopia. Why do you want to keep your coins in exchanges, when free online wallets such as Blockchain.com are available? If you don't mind spending $100, then you can go for a hardware wallet as well.
