They're...not going to ask your permission?
If you have an account there, they have a large central pile of assets, and a database row saying that you are entitled to X amount of those assets. Someone else has a database row saying that they are entitled to Y amount of those assets.
If someone breaks into the other account, and makes an illicit transfer, then Y goes down and the central pile of assets goes down. If crypto.com makes the other account whole, they simply increase Y back to the original amount. But the central pile of assets hasn't gone up accordingly. They just used "your money" to cover this, and they don't ask you for permission.
When you go to them later and say: "I want to withdraw my X somewhere else", they might say: "I'm sorry, we don't have X right now". That's a run on the bank.
Fortunately, we have protections around specific institutions to prevent these kinds of situations. Capitalization requirements, FDIC, etc. Unfortunately, if you have an account with crypto.com, none of those protections exist for you. You're banking on them having the funds when you ask to withdraw them.
