The limit for the bitcoin is the sky. About the new coin will be determined by the demand and supply but i was expecting a high price after the hardfork caused by another people that keep their bitcoin in the wallet can't send their bitcoin into the exchange site. So, those people are holding their bitcoin on the exchange site get the more advantage to sold their b2x at very high price,
That's about the early hype of the coin itself.
The chart of the bitcoin cash will tell you a lot.
