Without a HardFork the main prediction here is that the price will skyrocket. In few months Bitcoin can be pricing $4500 or even more.
But seems things won't happen so fast, we need to wait what will happen right after August 1, maybe there will be a delay of days or weeks until things come back to the normal as we see today.
Do you think that bitmain that try to apply UAHF ( User Activating Hard Fork) will succeed. In my opinion economic bitcoin will not receive push from bitmain. The hardfork can down bitcoin in very low and make lost interest for new buyers. Are all bitcoin users will choose hardfork? for myself I don't really like it.
