I have most of mine on an exchange because I'm getting paid interest. Has there ever been a time when an exchange like Binance for example, steals your funds or gets hacked and people lost money?
I think it is safe and has more advantage if you store it in a most reputable exchange like binance and houbi or kucoin you know that there is a lot of new exchange and it is a big problem if you store it in new exchange because you dont know if the particular exchange is scam or not, so i suggest to store on proven and tested exchange. Storing your crypto on exchange for interest is good idea keep storing and goodluck.
Although Binance is the most trusted cryptocurrency exchange, there is a chance that it will be hacked. On May 7, 2019, the world's largest cryptocurrency exchange, Binance, was hacked. The hackers were able to steal around 7000 Bitcoin, which is worth more than $40 million USD at the current price. The hack occurred at an inopportune time for the exchange, and it appears to be its largest hack to date.

This is a physical device, and you must tap the physical device button to enable 2FA. This is useful for those who have a large amount of money in their exchange account.
