I'm looking to gather information about what people would like to see when it comes to analyzing all crypto's. I was thinking about measuring percentages of increase between certain dates/ by volume/ measuring social activity...I'm looking for suggestions to help me build a tool for the community. 
Almost all the major exchanges have that tool on their websites.You don't really need to put efforts in creating something that is available in all shapes and sizes.I wish I had a personal bitcoin bot which would operate my desktop wallet.
