Saving your money in an exchange is not safe either because you are not in total control of that money, the exchange controls it for you, you don't own that money since it is not in your custody but the exchange custody, it's  more of not having your money in your possession like you are keeping the money in someone care or account, and so the exchange can do whatever they want with your money, and there is nothing you can do about it, what if the exchange computers get hacked, or decide to have maintenance exercise and in the process all you have is no more what will you do, who will be held responsible


Bitcoin was created and designed for you to have financial freedom and to be autonomous that is you having total control of your asset, that is why you are to withdraw your Bitcoin from an exchange into your wallet for safety and security purpose,you withdrawing means, having your keys that allows you to have total transaction and management control of your Bitcoin, which means no one else can control your asset other than you.
