There is only one coin, Bitcoin. There will be an update of the software, it will be well telegraphed, everyone will upgrade in plenty of time.
I am sorry Sir but for the meeting of central banks you can try next door, these are cryptoanarchists that think different.
I guess cryptoanarchists will have to support other real fungible digital cash/altcoin in the end anyway and leave the bitcoin to provide VISA scale transactions.
I am 50/50 on the fork. There might be no reason to resist regulating and centralizing bitcoin and supporting the Gavin's fork so bitcoin can go mainstream quickly. I mean why get attached to Bitcoin so much when we have so many altcoins, just pick the right one that suits you.
