Before I invest in ICO, I make a research about its offering. It must have a realistic plan and executable product in the future. Many ICO are being offered but doesn't have a working product, they state that the money they will get from ICO is being used to fund the project. If that is the case then that is automatic no for me. I treat ICO as an investment and not charity. I see to it that I minimize the risk of investing by researching about the company and the dev team behind it. What is also its edge on its rival considering that many altcoins have excellent features compared to others. If it has great potential and has innovation then I must consider it.
