Same as you, im always checking their website to see what kind of ico they offering, and checking who is the sponsor of the ico, who the founder, and what kind of product or service that the ico sell. Even sometimes i got a suggestion from my brother or friends im still double check it to make sure my self that i join the right bounty. And there is another way to check the ico good or not, you could see from the first sale of the ico. Some icos gives a bar of how many tokens that they have sell that time.
