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.
tjere are so many icos and on my opinion you will aleays find what you want if you will look for long enough so good luck
