Additionally, it currently seems SegWit2x will fork without strong replay protection. This means that post-fork, BTC transactions and B2X transactions will look identical and could both be valid on both blockchains. Therefore, spending coins on the BTC blockchain could make you accidentally spend the “equivalent” B2X on the SegWit2x blockchain, and the other way around. Instead of paying someone only BTC, you may unintentionally send B2X as well — or vice versa. The BTCs and B2Xs are initially “stuck together.”
