A few exchanges (Coinbase & Bitfinex) have already announced that they will disperse B2X to all holders of Bitcoin on the ex-date in a 1:1 ratio. Therefore, once the spread is put on, the physical Bitcoin purchased as a hedge should be sent to any exchange that will split the coins for you. This allows you to sell any B2X received immediately. 

On the ex-date (expected to be on or around November 20th), you will receive B2X in a 1:1 ratio.
