If no Incumbent Blockchain exists pursuant to these T+Cs, BT1 tokens shall be deemed to have a value equal to zero and shall be removed from the platform. All open orders for any BT1 trading pair will be canceled at Contract Settlement.
4.Settlement—BT2s: In the case of BT2, Segwit2x shall be deemed to exist only if a blockchain has diverged incompatibly from the Incumbent Blockchain. Any settlements of BT2 shall be to B2X. If no Segwit2x blockchain exists pursuant to these T+Cs, BT2 tokens shall be deemed to have a value equal to zero and shall be removed from the platform. All open orders for any BT2 trading pair will be converted into open orders for corresponding B2X trading pairs to ensure pricing continuity and minimize disruption for users trading BTC pairs on leverage prior to the Chain Split Event.
