How can we select non scam ICOs before buying?
Check their roadmap. Some scam ICO don't have any roadmap to present and that's suspicious. Some scammers use some pictures which is not them. They are just steal a picture just to present to us. It's better if you check their profile or better if you search them on google. Sometimes, they don't use escrows. Escrow is a must when creating an ICO.
These are some of the smaller things that are overlooked. You are about to invest your money into a company and some people dont even do a google search before investing. Please people, do your research before investing
