I was just thinking that since Bitcoins is 100% on the internet, what would happen if the whole world adopts it and 20M bitcoins gets stolen by a genius similar to what happened to Bitfinex?
The first reason that is not possible is because these bitcoin are spread across the world and not in a single platform like bitfinex and no one in the right mind will store their coins in exchanges or web wallets and if you know the basic on how to protect your system then no genius or crooks can hack these coins from anyone and if you cant do that,hope you have heard about offline and paper wallets.
