Investing in an ICO is a good idea, but before you invest you need to do your own reasearch about the ICO.  There are things that i consider personally before investing in ICO. First, i look up the product or the project itself, if its profitable, sustainable, accessible and  for every indivudal if it meet all of its one check for me. Why because the success of a certain product or a project is always the output or the end which is the consumer.even if the product is good but its not accessible to every individual its difficult to use its not gonna work. Second, I'll also check the company itself or the people behind the project or the product if they are equip to manage a company and also it will help me to verify if it is a legit company and project not a scam.lastly, the bounty manager who are managing the campaign.why? Because if the bounty manager manage the bounty the marketing strategy of it is good. Many individual will know what is the product all about or it became visible in social media.
I hope it will help you.happy investing!
