SCOT tribes can't work on Hive without a Hive sidechain.
That's why @aggroed is planning, and hopefully preparing a separate Hive-Engine and a sidechain to support it. Then the tribes will have the option to switch over and, yes, start anew. The tokens will not be the same. They can choose to do their own airdrop under their rules. Hive-engine can't and mustn't do the airdrop since it doesn't own any tokens.
My 0.02 tokens entirely :)
Thanks for clarification.
