forest for the trees...~
one of the biggest things holding crypto back from becoming mainstream is having that person/company come in and streamline the design.
between all of the currencies the only growth is with by adding money to the market cap. without this it will never break through the ceiling its been the last few years and is potentially a sitting duck in a way. most all currencies move in way form or another to the rhythm of bitcoin whether they react negatively or positively to bitcoins gains or losses in market cap the main point is somehow they are tied to this main pillar.
the point of looking at this from a design perspective is to find a real way to push into visually simplifying even if it is focusing on the dollar worth and not a string of numbers. what is the person in a starbucks line going to be able to relate to when they get to the register? a mass amount of digits or some sort of simplified version they could look at and understand. essentially its looking at some sort of monetary "language translator" that can tell a person spending bitcoin (hopefully alt coins as well) in real time what their "monetary language" total is at a register.
the more people that use this technology the more that comes into the market cap and the more early adopters like yourselves will hopefully be buying houses or paying off student loans with your crypto. i know i'd love to be and i think with a focus on the design, simplicity, and creating that visual that translates to more everyday type people (people currently not in the crypto market)~ will catapult crypto to a place we've never really seen it go before.
