I think we could add whenever the price is at new all time high

I noticed too that altcoins are not follow Bitcoin price trends which I think due to the attraction that bitcoin have all the less motivation for people to buy coins that rarely move in terms of pricing and history
Sooner or later, BTC will reach those levels where it will either consolidate for a long time or go into correction, and investors will most likely start looking at alts at that moment. As I see it, a full-fledged alt season is still just ahead, and many alts will likely have new ATH. I hope that BFG will not stand aside and will also reach a new ATH soon.
