Update:

Updated the post with information regarding LEO, LEOM, LEOMM that remains on Steem-Engine: Those tokens will be disabled for trading right after the airdrop meaning that you will only be able to trade LEO, LEOM, LEOMM on Hive-Engine and will no longer be able to trade them on Steem-Engine. Anything held in market orders on SE will be airdropped as liquid balances on Hive Engine.

Again, if you have questions about this, please jump into our discord or leave a comment here.
