I am worried about the price.Maybe it will be 5000$ within 2 days

Maybe it ll be 2k in two days. So what? You dont lose until you sell. So what is your best course of action?
Exactly! I just dont get all these frowned faces all over the forum whining about BTCs price fall! The trend will not always go down, it will eventually climb soon! Funny, because back in the 2nd half of 2017 when BTC was on a hiking spree, a lot of users wished that BTC price would go down to 6k, 5k, or even much lower so that they could get the chance to join the ride. Seems like their wish is likely to come true.
