Well, thats just the thing... Its not that Bitcoin isnt safe... Its that exchanges aren't. You can store Bitcoin in a cold wallet, offline, and there is no way ANYONE can get to them. In fact, banks CAN be hacked. Bitcoin store in the right way cannot. Cryptocurrencies are far better than bank accounts. To go a step further... People all over the world who do not have access to bank accounts CAN indeed have a Bitcoin wallet. They can also send money back home to families if they need to migrate to make money. Another plus for Bitcoin.
This post never meant to imply that Bitcoin wasnt safe, only centralized exhanges are unsafe :).
I would definitely look up an article on how to safely store Bitcoin for more reading. In fact, I think I will write a post on here later today :).
