494782 or 494784?
Coinbase announced: "The Bitcoin Segwit2x fork will take place when block #494,784 is mined. This is projected to happen on November 16."
and also "Will a new asset be created following the fork?
Yes. The result of the fork will be two different blockchains, which means there will be two distinct digital assets."

So, if, as you wrote, the fork "dies out", what will happen to all the money invested by new people like me today or in the coming days in this B2X ?

Will we lose everything?
If I understand you, the people who buy it is just a bet on if it will survive or not??
