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.
It is safe to store your funds in Binance or Huobi or KuCoin if your only other option is to store it in exchanges like YoBit and HitBTC and other shady exchanges. But you have more than just these options. You can actually withdraw your funds from these centralized exchanges into non-custodial and open source and hardware wallets where the private keys are under your sole control. So don't settle for relatively safer options when you could actually keep them in much much safer storage. You actually don't own your funds stored in centralized exchanges.
