My view of the bounty is now quite better and professional managers have now promoted it a lot with a very small allocation and also quite a lot of participants, but remember each payment has to wait longer.
Not only not promising but as well I find it a total waste of time since imagine you work with those campaigns for a month or more than that but in return you get less or worse you will not get paid since the dev turn scam and didn't list their token on exchangers. So its really good to make this as past time so that if we will not get paid then its ok since we didn't risk everything on it.
Although those reputable manager is good option for choosing the campaign but it will not guarantee anything since for sure we know that the one mostly do the distribution is the dev so all of this is a gamble.
