how long we should wait?
It takes long time to recover it will take maybe 1 month or 2 months depends on the environmental effects of the market. Bull needs time to recover to reach $14000 or break its all time high price and that's lambo. Bitcoin takes time to recover and it also needs our patience on waiting if we don't wait then it is our fault when we didn't get any profit because of that kind of attitude wi really bring you to a wrong side. Time is a must in recovering.
Normally when people ask me for the waiting time, I would tell them till they see the profit they desire to have on their investment, which may take longer than that I month or 2 months, in as much as we cant control the market or the factors controlling its price movement, except we are a big whale, it will really be hard to tie a particular time to it.
Tying time to it is what make a lot of people get discouraged and fall for panic selling when the time being speculated comes and nothing seems to happen, all I know right now is that the market is in recovery stage and with time and patience like you said, we will see our investment grow to it ATH too.
