In just 2018 millions worth of crypto lost because of the exchange vulnerabilities. Most of the crypto exchanges aren't regulated and your funds aren't insured. Therfore you should choose crypto exchanges carefully. In my opinion at the moment most safe crypto exchanges are Coinbase, Kraken, Kucoin. There are maybe other secure exchanges but these are the safest crypto exchanges which l know. If you trade with Coinbase or Kraken your funds are insured and also they keep funds in cold wallets instead of hot. TheФ safest crypto exchange in my opinion is Kucoin. In order to withdraw your funds from kucoin you need to use googgle lock, write three answers to your questions, confirm email address etc.
