There are many popular sites are available like Bountyhive,Bountylord that gives the ICOs announcement their duration time etc.
I want to know that how you select an ICOs to either participate in it as invester or a bounty campaigner.
well those sites are very nice but the problem there is they pay trash after participating in most of the project they handles, so i don't participating on any project handled by this parties due to there low payment moreover amazix i don't like doing there work any more.
