Segwit2X should go through without a hitch. 80% of mining hash powering are required to activate it, which currently there are aprox. 90% that are signaling for it. If Segwit2X has 80% majority code will lock within 2.5 days approx. July 25th. BIP 148 UASF will be unnecessary Aug. 1st but a good back up just in the case Segwit2X fails to activate. There could be two Bitcoins but unlikely after these two deadlines. Its clear 80-90% of market wants Segwit so if other BTC chain forms it will be immediately killed by majority chain hashing power.
****Remember best time to buy is when others are fearful. Even before Segwit activates all crypto market could double like what we saw in Litecoin even before Segwit was certain. If there are two Bitcoins after which I believe is highly unlikely its clear 80-90% of market will be behind the one with Segwit activation. Buckle up - the wild ride is here and its going to be crazy up's and downs over next two weeks.
