Might I add an alteration to the meme... a collection economic systems... crypto-currency could become maybe a single one... or maybe a patch work of interchangeable competing cryptocurrencies. Preferably done so they work with each other.... like maybe a video streaming coin that embed the stream in a steem post... for example... or maybe even opt-in charity coin models... we could fight for clean water... fight hunger... this is what interests me in steem and in bitcoin.
