I don't think it makes sense to call Bitcoin XT an alt-coin anymore than it does the current version of Bitcoin Core, which has hard-forked several times since it was introduced. Furthermore, Bitcoin Core will only fork away from Bitcoin XT when XT has 75% of the hash power behind it.
You gotta be joking. Bitcoin XT is the biggest scam-alt-coin ever made. Delete that shit.
Stop spreading FUD about hash power here and hash power there.
