LOL. That article is full of it.
They will just halt deposits/withdraws on Aug 1st in case there is a split.
So, Bip91(softfork) = chain split?
The signaling of BIP91 has the purpose of avoiding the chain split which already had the majority of the hash. Forget about BIP148 that related to the UASF.
I think that you must forget about the chain split and stop to make another member or holders are feeling panic caused by the word of chain split.
OP, Have you read the statement by theymos from the article that the link already mentioned in above of the homepage?
Someone will correct me if I'm wrong, but on top of BP91 BP141 et all which are going well, there is a minority who have decided to hardfork an 8Mb version of bitcoin on Aug1st. They've called it BCC (Bitcoin Cash). It's a minority initiative that won't have much impact if any, at least in the short term.
