Absolutely no! ICO is an alternative way to raise funds. Then if the project behind is good or it is underspeculation, it is possible to become rich but there are the same possibility to become poor if the project fails.
That's not true because ICO is the only way to increase your investment, also the only way to grow your coins. And in my opinion you can never get free money in this crypto world, so ICO is can help you to have plenty of money not giving you free money. And if you want to have a lot of earning try to invest in ICO.
