if BitPay will treat 2x coin as real Bitcoin and recognize its price as the price of real Bitcoin, than they will open themselves to a "fork attack" - people who will split their coins will pay to them with 2x coin and will effectively double the value of their coins. This might be a huge loss for BitPay, since they will have less value than they are giving to their users in fiat, because exchange rates on open markets for 2x coin will be much lower than for the real Bitcoin. Sooner or later, even 2x supporters will have to recognize their chain as an altcoin.
Bold prognostications, but only time will tell. I always hear the ideological arguments being presented in support of the "real" Bitcoin, but I seldom hear any economic argument and I think that might be causing the bias in your perspective. What needs to be considered is, for the people out there who have businesses to run, or for the users who rely heavily on making frequent transactions, all those ideological arguments may not have a great deal of influence over their decision making process. There are genuine use-cases and business interests to consider and BitPay just reiterated some of those. Money talks, as does convenience.
So, if there is an overwhelmingly significant proportion of hashrate following 2x, staying on the minority chain is the dead opposite of convenience. It's entirely plausible that enough businesses and users will weigh up the pros and cons and arrive at the conclusion that fighting against the current to preserve an ideological standpoint (that not everyone feels as strongly about as you do) doesn't make sense when considering the economic cost to keep fighting. It might not be the case that miners are "forcing" this decision upon a majority of people, it could simply be that there aren't enough people who care sufficiently about a 1MB blocksize to be in the majority anymore. The majority are the economically relevant ones, so are you absolutely certain that's still you?
If a hard fork had happened far earlier in this debate, back when the idea of 20MB blocks was being evaluated and dissected, I'm certain you'd be quite accurate with your appraisal of the "real" Bitcoin vs the altcoin, but now that it's been whittled down to 2MB (and considering a larger blocksize will probably be a necessary requirement to support things like the Lightning Network in the not-too-distant future anyway) and because there now appears to be sufficient support to move forward, or at the very least, certainly less opposition than before, there is arguably a far greater chance of success now.
The real question is, are
you going to try doubling the value of your coins via the method outlined in your post, or is it just idle speculation from someone who ran out of ideological arguments to make?
