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?
There are several exchanges in the crypto market that have gained a good reputation, one of which is Binance and the other is KuCoin. If you save your assets on these level exchanges, I would say that your assets are safe. Why, many of us may have heard in the past that these were also face the cyber attack, but still no one was harmed.
