I thought that a few days after 1st August everybody would have dumped it to make it go down as low as $0.01... but now it's still worth hundreds of $
you thought very right and everyone did dump BCH and price did drop. well not as low as $0.01 but it dropped hard.
but what you forgot to factor in, was all the big pockets that are behind bitcoin cash. Roger Ver and Bitmain have a lot of money at their disposal and Bitmain got a shitload of money because of the fork by abusing the difficulty adjustment or EDA and poured it into BCH.
and now it is just being pumped. mostly because of the upcoming SegWit2x fork and will probably have another huge leg up. but that doesn't change the fact that it is still an altcoin and is getting pump and dumped.
