Also there's a little chart i did by digging a little bit, i took in consideration the % from high to low and the duration from the ATH1 to ATH2 so we can have an estimation of the recovery duration, so there's what i came up with.
Juste don't pay attention to the green 90% actually it's +1000%
My personal opinion, though, is that Bitcoin still has a long ways to fall primarily because of the huge run-up from the "alts". I'm sure there are many of these coins that are little more than cash-grab scams or theoretical ideas that have no plan in place and those have to dissolve and they will bring BTC down with them for awhile.
The long term view though is quite good, but there is no firm "bottom" to how Bitcoin can go nor to how high. You just have to be patient and follow the longer trend. BTC still seems to have more bad days than good, so I'm staying out until it has positive energy again.
