Don't panic, but your Bitcoins may just vanish into the ether next month

The community-driven organization overseeing Bitcoin on Wednesday warned that any Bitcoins received after Monday, July 31, 2017 at GMT-0700 may vanish into thin air or be rejected as invalid.
Bitcoin.org said that at the end of the month, Bitcoin confirmation scores – a number that represents the difficulty of altering the associated transaction – may become unreliable for an unknown period.
"This means that any Bitcoins you receive after that time may later disappear from your wallet or be a type of Bitcoin that other people will not accept as payment," the group said.
