ICOs are getting mature with their operations,most of them are handling it properly like an ordinary startup with legal consults.
Promising or not, ICOs is still a good way to get funded. I would consider ICOs as well if I really want my idea on board.
There are a lot of icos who are really serious about their platform and because of that we should not lose our faith to them, Maybe there are also ico who are not continuing their project and some are also scamming their participants so you should also look for manager that is trust worthy for the campaign as well as developers.
