Traders speculating on the pending ETF if positive will push the price of bitcoins and the whole cryptocurrency market into a bull run and if it become possible for endorsement of the ETF by SEC then bitcoins will be heading to the 20,000USD.
Looking back at what happened so far, there are always pumps before the announcement. Then the ETF gets rejected, price goes down. Manipulators know this, so they will essentially place sell orders that day and reap in easy cash.
