As many of you already know it'll happen at the block 501.451 so make sure to store your bitcoin on a wallet/exchange that will support the fork.
You can check the bitcoin block explorer if you want to know exactly when the fork happens.
At the moment the segwit2x futures are being traded around at 350$ after taking a dive from around 1200$.
BTC holders will receive not only B2X in the ratio of 1 to 1, but also a proportional number of Satoshi Nakamoto`s Bitcoins.
Cheers
