Today, I have received an e-mail from GDAX that says:
We wanted to remind you that the upcoming Bitcoin Segwit2x hard fork is projected to take place on November 16 and will result in two bitcoin blockchains.
And especially interesting:
Any customer storing Bitcoin (BTC) on GDAX at the time of the fork will be credited with an equal amount of the Bitcoin2x (B2X) asset on the Bitcoin2x blockchain. GDAX will continue referring to the current bitcoin blockchain as Bitcoin with ticker BTC and the forked blockchain as Bitcoin2x with ticker B2X
Does this mean that I have the double amount of money after this fork? If yes, why should I not buy a lot of bitcoins before the fork and sell all Bitcoin/Bitcoin2x immediately after the fork?
