I have a lot of doubts.

First, my BTC before the fork can be translated to XT any time (if its my will). I have a BTC mining contract, after fork BTC mined cannot get converted to XT, am I right?

What happen if I buy BTC on a exchange after fork, I'll be able to convert it to XT?

What would happen if I dont like XT or XT crash, may I come back to BTC?

It is possible a market manipulation? Example: A group of guys make buying pressure to pump BTC-XT, they convince a lot of people to change to XT because have best prices, then dump the price and run out?
