BTC divided to BTC and BCC, and will be divided to BTG and B2X.
1. B2X will become real bitcoin?
2. More BT* will appear in future?
No, B2X is an altcoin
Unfortunately not quite. You can just B2X as the altcoin, but rather after fork which ever chain has more hash rate and miner support will be the real BTC technically. Though this BTC will remain as the legacy BTC if that happens. And in the end it all comes down to the community, which ever chain they choose to be real BTC, that would be the real BTC.
