Guys, faced with the project, took part in the bounty, the result of Scam. Took part in another bounty company, there ICO ended more than a month ago, and the payment has not yet been the bounty Manager is silent...Apparently this year's bad in respect of ICO projects.
I think it depends on the bounty manager and the admins of the project. There are a lot of promising projects but the admins may be scammers. Such a waste for some good projects though.
Maybe you should join their telegram channel or follow them in twitter so you may know your bounty's updates. Also, do not join bounties without thinking. Do some research especially on the bounty's admins.
