In the end the client will be decided by the exchanges not the miners.
What miner is going to mine a coin that then can't be sold on an exchange?
The same pretty much goes the other way around. I think it's fair to say that the different parts of the ecosystem depend on each other.
many don't understand that the new code in XT will be active only if 75% of the network actually runs it
And many don't understand that the 75% is not of the network but of the mining pools. And this can be easily manipulated!
Anyway, XT altcoin fork is dead now. Block size debate was just a cover up now revealing hidden agenda to introduce among bitcoin users the XT client that is simply an IP logger and blacklist aggregator!
Well, I said this few years ago, Bitcoin is not BitTorrent, bitcoin is a financial instrument and will be heavily regulated, you can try to fight it now, but whether you like it or not, these things will eventually happen... or Bitcoin transactions will be deemed illegal and businesses will be forbidden from using it, and there the mass adoption dream vanishes in front of your eyes.
Let's wait and see if any of this is true. It reeks of sensationalistic fud. Or just some conspiracy theorists going off the rails again. Which is odd, since bitcoiners are such level-headed people.
