Why are investors more likely to hold Bitcoin in exchange wallets?

I know the truth is that some investors are holding their assets on a centralized exchange for reasons known to them, but it is also important that we make it clear and bold enough for them to know the risk ahead when using a centralized platform. The risk it poses does not warrant taking such a decision in this manner, but I don't know why many will always choose to go this hard way when they know the possible risk in it.
