Highly! I am very strict about the choice of ICO, because there are too many useless and scammers in this direction. Look at the number of ICOs that enter the market, it's just worth carefully selecting and allocating 10-20 criteria for selecting projects.
in any case, the company must be positive and have real results on the exchange after the sale of the tokens. But in any case, any study of information and analysis will not be an absolute guarantee that this project will bring profit or prove to be not fraudulent.
Yes company need to be positive in other to have a real good result after the tokens get listed on exchange site but it all rely on strategy and working simultaneously planned by the team. However, there are particular people who are good in proofing the legitimacy of a project and ones just need to do a deep search either.
