...should we buy it?

Because as I read, if there's no replay protection, so for every B2X dumped, there will be a equal number of BTC dumped. If someone sell one B2X, they will be selling one BTC to the same recipient.

When you sell something, someone is going to buy it. But who is going to buy B2X? Probably the ones who are behind this attack against the network. They want it all for themselves and they want it cheap. But the fools still want to dump B2X and wont listen to the warnings about the lack of replay protection.

The exchange will have the obligation to deliver it. For every B2X bought, a BTC shall be delivered. They will break for sure, but they will have to do it, or people will sue them.

Now what I think, is that they, the exchanges, will be holding it. For every B2X dumped, there will be a equal number of BTC dumped as well, but such exchanges will hold it and not deliver, becoming rich at the expense of others.

BCH was a lure. People are deluded thinking it will be the same this time, that they will have muh free coins. Its a trap.

Maybe the price of bitcoin will not be affected, but people will lose their money, and this will hurt trust on the network, which, I think, is very important for it to endure.
