You should learn more about how to save your own coins. exchanges risk you losing your coins and losing your money. you should read the suggestions of everyone in this forum. they give a lot of knowledge.
of course all the advice given is very useful. But saving some assets in exchange has the risk of losing assets, but if the exchange provides security guarantees I think your assets will remain safe. every exchange has a level of security that I think is also not easy to be damaged by people, they built a security system that I think is strong enough.
