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.
$4500 wow, i like this prediction, lol, this will be magnificent, and everyone should be extremely happy.
But if a hardfork happens? I think it's ok, we get bitcoins in each blockchain...
