The Bitcoin Core development team warns all bitcoin users about possible instability in the network on August 1, when events will occur that should determine the future of bitcoin in the coming years. Official warnings from the cue ball team are published here!.
The bitcoin network can be bifurcated and remain unstable for an unknown period of time - this means that any bitcoins that you receive after that can later simply disappear from your wallet. All this can happen in the event of a failure to activate SegWit2X, which can lead to network sharing. I recommend that everyone stop any operations with bitcoin for a couple of days before August 1 and a couple of days after. This will give time to confirm all pending payments in the bitcoin block before the activation of SegWit. Beware of scammers who will offer to invest in "bifurcated" coins. And such will be, believe.
P.S. forewarned is forearmed!
