An initial coin offering is similar in concept to an initial public offering (IPO), both a process in which companies raise capital, while an ICO is an investment that gives the investor a cryptocoin, more commonly known as a coin or a token in return for investment, which is quite different to the issuance of securities as is the case in an IPO investment. Do you invest in ICO? and has you make money from it?
I don't want to announce that the golden days of ICO is over, there are still good ICO around, but unfortunately, there are so many ICO around us that it's hard to pick the right one that is going to make an impact in the market, investors now prefer to buy these coins when it hit the market, because it is where the real value of the coin show up.
