Even a 65mio $ hack could drop the btc price for about 10% only one day.
I think bitcoin has proven to be a save investment.
it was about 120,000 got hack. if all dumped, yes it will not matter, because the volume of bitcoin in one day about 200,000. so the price of bitcoin will recover soon if it is dumped. like yesterday when the price down to $530 during the panic, and now has recovered to $570.
