Bitcointalk is a good place to collect investment information, I think I will not waste more time going to other forums, because bitcointalk has the most resources available to me.
Indeed, this forum provide many information about ICOs. Most new ICOs always giving information about their project or the developers team information in ANN dashboard and i think from that we can gain many information. Beside that, forum user always give feedback and its useful for us before making decision to invest or not
