Thanks @campell. Let me answer your questions.

First of fore most, Veil has higher potentials of lasting the test of time... Check out Veil labs and what they stand for. Also check out those technologies employed in Veil. The likes of Zerocoin and RingCt and bitcoin's dandelion protocol ain't child's play.

Yes, citex is one of the biggest Chinese exchanges with volume. Trading your Veil coins there is cool. It has minimal charges compared to other exchanges.

Apart from purchasing Veil, you can join it's bounty program and participate in any of its campaigns. I'm not aware of Veil airdrop. Here is link to the bounty thread: https://bitcointalk.org/index.php?topic=5125073.msg50334607#msg50334607

No you can't. To earn anonymously and judiciously staking Veil, Veil coins should be in your veil wallet.
