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.
general knowledge, the whitepaper is there, the team is there / is clear, the transportation is there, if there is a sponsor it is better, and the most important thing is they show that the sales ICO is in progress
