Is it dangerous to store ETH on Coinbase or similar?

I’m brand new to ETH and have started investing more and more when i logged into my Coinbase account from two years ago which i used to buy and sell CSGO skins and found a very nice amount of eth. Now that i know i have it I’m worried it’s not safe/ would be safer on a hardware wallet. Is this true? Or am i fine to continue using Coinbase for investing in ETH? Any help is very much appreciated. Up until now, eth didn’t sit in my Coinbase account for more than a few minutes as i used to to purchase CSGO skins/ cash out.
