With new ICO project, I research all of things around ICO such as White paper, Technology (Blockchain is popular), Management Team, … I think they are all important. After researching, You can make your own decision in investing any ICO exactly.
Oh i heard that Facebook will make its own cryptocurrency. Don't have any certain proofs for that. I don't agree to remove all ICOs and bitcoin out of Facebook. We should divide them into good and bad ICOs to invest.
