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.
Now to know exactly the good ICO project to join in is very hard because there are too many project every days. Each person will have their own reference channel. With me, I usually participate projects of KrypitalBounty and Amazix Bounties
