Ducatur Airdrop
Finally, a simple solution to connect blockchain and business.
Good project but the bounty isn't the best. There are a lot of small restrictions (e.g. max. 1000 points per day), the long time (until June 30th) and the bunch of tasks which makes it quite unattractive to participate. A common problem with bounties is that you don't know how many will participate and how much tokens you get.
