This is an example of too much confident on storing all of his bitcoin in only one exchange. If you are a holder, try to explore those exchanges or wallets which are really safe in storing your assets and you will not have any fear of getting hacked. You always need to have a plan B or other wallets or exchange where you can hold your bitcoin so that you can still secure your assets when something bad happens on your bitcoin.

But still, Coinbase is good because it has a lot of users, but Binance is really what I'm using for 2 years.
