In my opinion, in the last few years, I have never or never experienced an airdrop or bounty program again, unlike the following year, in 2017, the bounty or airdrop program is quite good, but ... this year we have to think long to participate in the program this. airdrop or bounty because we know that there are many programs that are not promising now.
Everyone will know everything after researching or analyzing all Airdrop and bounty programs, not just guessing at will, and if I may know how many Airdrops and bounties did you analyze this year?
