Sell now or cry next week.
Right now price is under 6700$.
If you LOVE losing money, Keep your btc, whales are laughing at you.
Even though bitcoin falls in the price of 5k, I will not sell it, because I think this is not the end of bitcoin. If you want to sell the bitcoin you have, it's up to you, but when bitcoin can rise to a better price, then do not express your regret for selling at a low price.
I do not come up of thinking for now that bitcoin will go to $5k. Well others may sell their btc to cut loses but mine I am still holding. Yes do not feel regret if price suddenly increase then you already sell yours.
