There is no way to fork BTC. There is a number, say $10M in market cap, cross that line and the base code is forevermore fixed.
ALT coins are the solution to fill voids not featured in BTC.
Unfortunately there’s a loud minority within BTC community that wants all market sectors (including micro transactions) and will likely kill their golden goose if a fork is attempted.
