With all these said, what are your opinions on this subject matter as I feel this needs to be looked into for possible measures to be taken for so as to further prevent or minimise the rate at which exchanges get hacked or being careless with investors and traders funds.
Given that a centralized exchange has full power over the coins you send to them, there's always the possibility that they choose not to give them back to you. They can lose your coins, or they can simply decide to keep them for whatever reason, maybe the government wants to freeze your account, or whatever.
Bitcoin allows you to have full control of your own money. There's no need to give it to 3rd parties, as it defeats the purpose.
So, to answer the question, no. It's never safe to give away your coins to a third party because you need to trust them. Bitcoin was designed to be a trust-less system.
