Yes, it is something that make me think a bit too... but yet BTC is much higher than it was 3 months before. I think we should judge in a longer time span.
Leason learned that bitcoin cash dramatically price value increase is just another pump and dump strategy that failed. For sure people that behind this strategy will going to lose a huge investments because instead of attracting people to sell their bitcoin and buy bitcoin cash due to sudden price increase, the result is opposite that instead BHC holders immediately sell their coins while price is at high which in result bitcoin cash back to its 3rd place right now and continue falling.
