What pages, channels, blogs etc?
For me i will choose thru the best known campaign managers with no negative trust. Campaign managers will do the most research about the ICO before he accept the task of handling the campaign because their reputation is at stake that if they handle a bad ICO it will reduce their good ratings but if the ICO is successful many participants will going to join because they trust the campaign manager.
That is the most important with no negative trust. An ICO is very helpful it run a development to the community. In joining an ICO is a resposible obligation which takes task to do. Their are ICOs which is very helpful to the commumity that gives a stable life to everyone. They have said their are scammers but I think it is easy to identify if you gather informations.
