PLEASE CHECK ADDED 2017 PICTURES IN COMMENTS
In the 2017/18 Bulltrend BTC tended to dip between -30-40% several times
As we see one bigger correction started at ~2x ATH and was at -38%
Since 2019 it seems to have changed to 20-30%.
-20% would mean we correct to 33k.
-30% would mean we correct to 29k.
I believe that this could be the dip-metric for this bullrun, because, as gains getting smaller, so will dips.
If we would get deeper, i think -40% (~25`000) would be the limit.
