However, because of BitPay's influence I think the "economically winning" chain will be the one BitPay chooses.
I'd say of all companies it's Coinbase who wield the largest phallus. They have a history of being somewhat wishy washy too.
I've no idea about the various forks, but if Bitmaincoin wins out then I'm done. I didn't sign up for that. I didn't sign up for most of what's developed but that would be the final straw.
