When Classic will get activated, I doubt anyone will stay on the 25% chain. That chain will end up being 0.
assuming that classing will gather 75% of consensus right? where are the bettings on this?
there are data that show that classic is so far ahead than unlimtied and core?
No data yet. Mostly vocal support from a majority of mining pools and the broad industry at this point. That's why Classic has the most chance to get activated.
