From my understanding with the Airdrop...
Just need to have the coins (at least 10) in the wallet and that is it, at some point in time on Monday, the drop will transfer over, correct?
Or is something else needed?
As long as you have min of 10BTX in your local wallet, you will get your 3% airdrop directly into your wallet. You don't have to do anything else other than to have that amount of BTX in your wallet. Keep an eye on the thread for announcement from dev as there are plans to change the drop method at some point. For now, all remains as stated in the OP.
