Is this a prank or what? Why do you say people should withdraw funds from top ten exchanges without any relevant point.  Well, I don't hold funds in exchange wallets for long, unless when I need to trade since centralized exchanges are open to hacks. In as much as this post looks more like a prank, it should pass a message to everyone storing coins in centralized exchanges. Never leave your coins in exchanges unless there is need for it (trading, swap, etc).
