BTC a list of automatically check-in sites for retweet reposts by Bounty 
https://bountyhive.io - it's hard to join the company because the limit is very fast, good companies are good. It's not clear how they keep records
https://bountyplatform.io/ For me the best platform. Everything is convenient, everyone thinks themselves every 24 hours plus select promising projects.
https://bounty0x.io/ A lot of things, it's not clear how to keep records
https://icoreward.com Everything is also convenient, convenient to consider, adequate rules. At the moment one company is available
http://tokengoplatform.com - The site has its own coin, as well as 2 third-party companies
Who will tell you more???
I have used the first 3 and bountyhive does show the amount of experience they have in this industry which makes them my favourite because everything is professionally handled but as for bounty0x, it's a different story and I wouldn't waste time with them because they don't follow their own rules, they bend them whenever they like and grading of bounty work is done by anyone if the sheriff work is delegated to you... which makes it a weakness imo but I understand that's their concept but it's a flop, and a playground for many shit coins https://bountyhive.io - it's hard to join the company because the limit is very fast, good companies are good.
