I understand your point, but this rise in such little time is very suspicious.
Also does not explain, why BCH went from $2,800 to $1,500 in 30 minutes, when korean exchanges were down. No pumps were possible.

Probably DDoS attack on mayor Korean exchanges that were down twice last 24hours, otherwise trend would continue and most probably will continue soon. Same happend on bittrex - there was a gap, bittrex hanged and suddenly price dropped
