Well you can't expect it to ultimately rise after its been available in the market. They are giving away tokens by airdropping so expect some price to drop but I think the airdrop is just for marketing purpose, the team knows its price is going to dip low as possible. If you believe in this project, keep buying more because sooner it will be profitable for you.
Airdrop is just a marketing term, the airdrop was really a second bounty campaign. Those that received tokens were required to perform social media tasks like following on twitter and retweeting etc. Such tasks were verified before tokens were awarded.
