predict=bitcoin after touch 40.000 will start crash 2 to 20.000

our calculation show bitcoin will go to 40.000 (butterfly pattern) then 80% will start down trend to 20.000

advice=looking for sell from 40k to 42k ...dont close it with little profit ,hold it 30 day until 20k
golden place, 100% wintrate= on 20k to 18k looking for buy to hold min 3-5 month


keep monotor AC on daily chart and on 1hour chart(dont trade with it, 8month monitor it
if your platform dont have AC ,use stochastic 7.4.4
