I am not going to go into debate.
Crypto.com founders have a track record of shady business, they screwed their previous token investors (MCO), they spend more money than anyone else while having less volume/users on their exchange and blockchain.
Finally, I did use their Credit card and yes their app works well but that does not mean they are a safe product.
I might be wrong but I do not think so.
In any case as you said not your keys not your crypto.
I do not mean to FUD but this exchange is the most obvious scam to me.
Sorry
