There are many exchanges that has been hacked in the past, even a new exchange called Altsbit has been hacked this year and many cryptocurrencies were stolen. During most hack, cryptocurrencies were stolen while few stole users login details. This makes exchanges even more vulnerable to hackers as they are now the primary aims of hackers. Even from the list, I was so surprised to see some of the giant exchanges to be there.
In 2020
This year, 2020, Altsbit was hacked, this is a new exchange and was hacked not long after it was created, this hack was in February

When I read about this hack on
https://selfkey.org/list-of-cryptocurrency-exchange-hacks/ it comes to my mind that any exchange can be hacked, because the ones that have been hacked are many in number. So, I come to the conclusion that it is better to store cryptocurrencies on hardware wallets, and that exchanges are only for trading, not for long holding of cryptocurrencies.
Well, it's not recommended to leave your investment in a exchange for the long term since I've seen a lot of exchanger closing because of the movement of the price market.
For exchanges having a lot of funds in their wallet at least, they should make sure they getting secured for their own and their users. For sure it would be easy hiring some people to do this since they might earn a big profit in their exchange.
