It's just an advised to you, There are a ton of ICOs out there, with every single one of them promising huge returns and useful perks for potential investors. But before you get carried away and start sending your hard earned money to every single project out there, remember that many, if not most of those projects will inevitably fail or will turn out to be a scam.  Keep in mind that all cryptocurrencies and the Ethereum platform, in general, is basically an experimental technology. A vast majority of ICOs are reliant on Ethereum, and they themselves are a very experimental mechanism. It’s an experiment on top of an experiment.
A typical project holding an ICO will have a website and a white paper, containing as much information about the project and its goals as possible. Those will describe the team and its relevant experience, the idea and the roadmap of its execution, approximate goals and means of reaching them, and so forth. Do not forget to note this every single guide on anything even remotely related with cryptocurrencies will give you this one simple advice: don’t commit more money than you can afford to lose. Thank you...
