Well the best thing to do is to make your own research to Projects you want to Participate with , because if you rely those reviews to ICO sites I can say their is a huge change you'll get scam , If you are looking for good ICO i would suggest WPP Energy which is a renowned company for providing renewable energy they do have several Project that is already implemented to partnered Countries to improve their Power Plant Sources by adopting Green Energy solutions to help users to access for cheaper cost and also helping to preserve out mother nature !
