There will probably be an address (3Bit1xA4apyzgmFNT2k8Pvnd6zb6TnwcTi) , if included as output, makes the transaction invalid on the SegWit2X chain. So splitting your coins is very easy. The whole no-strong-replay-protection argument is fake. SegWit2X was designed to be Bitcoin, take over the BTC symbol and be compatible with all wallets and therefore must not have replay protection.
Interesting, I wasn´t aware of that!
I ultimately think that the outcome of the fork will depend on the exchanges. If they list SegWit2x as BTC the outcome should be pretty clear.
Do you think the big exchanges will do this? Bitfinex is as far as I know the only big exchange that has already released a statement and it was
pretty ambiguous.
Additionally, it amazes me how divided the community is on the whole fork topic (even more than on the Bitcoin Cash hard fork). If we only look at gambling site / prediction market operators we have a few
sites like Fairlay that favor SegWit2x and on the other hand several owners, who heavily oppose it.
