Not every ICO is scam but I am sure there are more scam ICO compared to the legits. The trend is horribly increasing and I am afraid of its effect on the investors. If it continues, the investors would likely not risk putting their money in ICOs and this will result to no more bounty campaigns because no one will pay the managers. I really think ICO whould register first to the Securities and Exchange Commission or SEC as a proof of legitimacy before the launching date.
