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.
ICO is the most important strategy followed by the owner of coin to popularize his coin in the market then launch this exchange and chances of growth of coin rate increased by 50 to 60%.
