I believe many people invested in Bitcoin recently (that pumped up the price) as they wanted to double their coins due to 'fork'. I know people taken big loans (10k-20k$ or more) expecting to make a quick profit alike it happened on Bitcoin Cash. If 'fork' will be cancelled then the same people will be forced to sell their bitcoins to pay back their loans. for that reason I believe price of the Bitcoin will go down.
"2x Called Off: Bitcoin Hard Fork Suspended for Lack of Consensus"
Yes and No. In short-term perspective price will move up but on long-term I still expect BTCUSD to move lower ~4900$.
Observe Bitcoin Cash as money escapes from Bitcoin to Bitcoin cash.
