I do not think so, because there is no secure system, even bitcoins can be hacked, through an unsecured exchange.
You can say it's not but that is mainly the people's problem whether they have to leave their Bitcoin on any exchange which is allowing the hacker to give your Bitcoin on them once they hacked the exchanges. But if you know how to deal with this, you should have taken that remaining Bitcoin on any exchanges that you used and put it on your hardware wallet and viola your Bitcoin is safe with you unless you give your private key to someone.
Yeah bitcoin itself is safe and not hackable but the person who uses a bitcoin are the one that is responsible if ever his bitcoins will get hacked because he maybe store his bitcoins on an online exchange or a wallet . That isnt a good way to handle bitcoins but its okay if you will be using your bitcoin actively for trades or for business porpuses .
