It's based on a combination of context-controlled sentiment analysis and aan advanced cryptocurrency NLP and Machine Learning discovery engine that enables a user to automatically generate a token basket or “mini-index fund” made up of cryptocurrencies that are related to trends in news, global and local searches, concepts, context, keywords, hashtags, social media, URLs and other dynamic content.
