The scenario that Bitcoin drops down significantly in value would have the price of BCH bleed out back down to yearly lows of $181 support
If Bitcoin dumps BCH will hit that level but nothing more than that this is the bottom. This support zone is already marked as the bottom and $213 should hold out but if not that's the play to make.
The other scenario that this is the bottom at $213 this would make for a great LONG entry because this is the same level as before the pump in August. BCH is actually lower than what it started at the moment
