Looks pretty good to me. If btc has a pullback that looks like it might mindfuck everyone into shorting, then rest before it continues up, in that time this can develop further if btc dominance continues to chill out. Should BTC get a serious move the the upside the alts will get rigidy rekt probably resulting in this bnbbtc structure creating a bigger bull flag on a higher resolution of time. But if btc gets too mental, the pullback can also be something to suffer alts.
Although i am not trading this in particular, if i was to i would be entering in multiple times until i secured a position under my own digression
Anyhow it seem to be loosely following my scribble prediction
