I believe there are other people who have "lose" more than $60k as effect of bitcoin price. There are some people who always trust bitcoin no matter what will happen, so they just kept their btc for long term and some are not. If you can't hold any longer, just sell your bimtc right now.
Still, i am believing Bitcoin because even though i lose the value, i have strong faith in Bitcoin. I am holding my Bitcoin for more than 10 years instead of selling low in price in the market. So it is good to hold them for more than 10 years instead of losing faith for short term.
