China has already banned ICO and Canada government has already started cracking them down. Which looks like a proper step to me. If it can't be regulated now, it will become a ponzi market and people will start loosing big amounts of money. Invest in ICO but make sure they have a legal business to back them up.
Some random Devs create the ICO and know they can make some money and run off with that money and leave the Investor penniless. Acts like these justify the reason why Countries like China and Canada are clamping down on ICO's or ending the program all together!
