Most likely BCH has nothing to do with this crash - it has anemic trading and exchange volumes vs. Bitcoin/Ethereum/Ripple and this altcoin alone couldn't have caused the crash. The truth is very few know what really happened but they remain silent. This might be tangentially [bitcoin.com] related but only tangentially. Another possibility is that someone(s) has dumped a lot of crypto-currency on to the market and there's only enough money to keep the exchange rate.
Next bubble will be Pokemon Futures.

This one's my favorite.
The hard limit on Bitcoin money supply will be the temperature at which ASICs melt.
