The cryptocurrency space consists of an overwhelming number of projects, many of which consist of little more than a whitepaper and roadmap. Blockchain technology is still young and, as such, the majority of projects are very much work in progress. Bearing in mind that some projects are further down the development line than others, which cryptocurrency projects do you consider to have the best working product at present?
