I think to invest in ICO is a good idea. However, you should be very cautious and study carefully the who information about the project. You should pay attention to the amount and type of content displayed on the website. A good ICO will ALWAYS have quality and in-depth information which clearly explains what the particular ICO is all about. Then you should pay attention to the information about the founder and the team. It is very important that the ICO be founded by someone who has had prior experience in the relative field along with a team of strong developers and legal advisors. LinkedIn and Medium in particular are great places to check out the professional background of the ICO team and their expertise. Then they should also have a very good whitepaper. You can also see which large fonds and investors have decided to be a part of the Initial Coin Offering. And you can also learn about escrow or other ways to protect investors. You can also pay attention to professional reviews and rates in the rating agencies.
So, if you study everything in detail you can make a good profit from investing into an ICO.
