Traders never cease to amaze me! When it was clear that BCH will appear, BTC will continue to exist as 'bitcoin' and everybody will get free money, the faint hearted shaky hands sold their bitcoins below 2500 just before the fork losing big time. Now, the conflict between 2x and core is endangering the existence of bitcoin, these same traders buy above 4K!!! Little they know that if S2X forks without replay protection, the fork will be a giant mess, both chains will be unusable for days, possibly weeks and the price will crash (maybe even below 1000$). a lot of people will hedge into LTC, ETH and BCH! It will look like bitcoin is dying while BCH is going up like crazy. Of course everyone who supports BCH wants exactly that! (At least the ones who can think that far and are interested in a high BCH price). The recent rise of the BTC price is just a bubble, created by chinese mining whales who want to sell high all and then dump BTC for good. They are free now from the limitation of the core team and can adjust the difficulty to make much bigger profits. Reading between the lines in Roger Ver's and Jihan Wu's tweets, they will trade most of their BTC for BCH and will continue to drive up BCH's price.
No replay protection means there will be no alt coin. When you transfer from one chain, it will also transfer in the other, but if they have different address structures, the ammount you transfered in the other chain will go to another address, which can ou cannot be linked to the address you sent in the original chain.
However, if you never use the other chain, there will be nothing to worry, as most nodes are using Core software. Only those who install the forked software can get rekt, as the address they sent can be one of Core, whereas in the forked chain it can be from another person.
Just dont install any software which is not Core signed. Now how will we explain that to noobs who use bitcoin from cellphones?
