So seeing as though everyone (the majority) seemd to say they were going to sell their BCH and buy more BTC then why has BTC stayed down and even down more than it was yesterday?
Well, I actually expected the opposite: I thought Big Blockers would sell massively their Bitcoin to buy more Bitcoin Cash and move the price down. I hoped to grab some BTC at <2500 or even 2000 $ - well, it didn't happen. My theory is that Big blockers/Bitcoin Cash fans are still not 100% confident in their currency because of the long block times, low hashrate and centralized mining that in theory could favour an attack.
But actually, I think both movements are compensating each other: The "Big blocker dumps" hold the Bitcoin price in the
2650-2750 area - a very good price considering the latest events and only 10% below the ATH - while the Bitcoin buys by Bitcoin Cash sellers helped it to not fall below $2600. So both parties are actually contributing to the stability of the coin of the opposite side
