"In my opinion, buying in ICO is better if we are really ready with all risks, for the risks in ICO is bigger than buying coins in exchange such as getting the scam ICO. However, we can get bigger profits and bonuses if buying coin in ICO. On the other hand, if you don't wnat to have big risks, I think that it is better to buy the coins in exchange. Pick the top listed coins in the exchange to get profits. Briefly, buying in ICO or exchange is actually good depending on how our strategy and readiness of the risks.
