For those still wondering what BIP, UASF, August 1st means to Bitcoin
A group of miners, developers, investors, and bitcoin users will upgrade the Bitcoin protocol as specified by the User Activated Hard Fork (UAHF).
Those who do not want to follow our lead are free to use whichever chain they like. Miners implementing the UAHF will safely split away, creating a new version of Bitcoin called "Bitcoin Cash".
All current Bitcoin holders will automatically own Bitcoin Cash. The existing ledger at the time of the split is preserved, thus users retain any balances they had before the split.
