The spreadsheet collates ratings from the most respected ICO reviewers on the web to come to an aggregated score of upcoming projects. Ranked by both appearances and by average score the sheet lists the ICOs that are highly rated and those that have gathered a lot of coverage.
Please use the comparison spreadsheet as one of many tools to help with your due diligence. If you're considering any investment especially at ICO stage, always get involved with the communities, read the whitepaper and scrutinise every aspect of each project. If unsure about anything, head over to Telegram to ask the teams directly the questions you cannot find answers for elsewhere.
