Friends are greetings to all! I am very glad that there is such a topic for the reference. And I hasten to share my bounty platforms and platforms for airdrops!
1) icoreward renamed into bauntyhanters is a good and convenient platform! it can be seen that the team is focused on long work and leads to periodic improvement of the platform! already received from there tokens for participating in the bounty! very nice and comfortable design! https://bountyhunters.io/user/register?ref=2319
2) no less interesting, and maybe even more interesting will be the platform! the team is also constantly improving the functionality and operation of the platform! repeatedly received tokens for participating in bounty companies! https://CX/r/Kirgiz0444
3) the platform is a little difficult at first glance, but figuring out to adapt easily! there are a lot of tasks for every taste! also received tokens for participating in bounty companies!
  https://alpha.CCX/ when registering please indicate the promo code 2c985e (this is very important)!
4) This is a convenient and simple platform for Airdrop! the team carefully chooses them! already received tokens on the purse not once! https://tokendrops.com/?referenceCode=cedf4eae1489d7f3d216620343aa132d
5) it's a bounty with a private office! put it here because it's a platform for sports betting! register and get a personal account for bets with your token! I really like this idea! https://www.bethereum.com?r=GAQLDXB

So far, that's it! If, then I'll try something else I'll write! but also you write if there are other similar platforms! all the big money! I am sorry for my English!
