Really good article. I like to see mainstream articles such as this discussing the many benefits of crypto, they are few and far between. Crypto, wow wildly unstable as of today, could be a very stable currency in the future with the right structure and technological advancements.
BTC I can definitely see becoming the digital gold and a store of value. It's worth would have to skyrocket to many, many times it's current value if it would indeed become a globally backed gold for instance. There would also need to be a globally adopted currency for day to day transactions, and here is where a fortune could be made. A currency possibly like Steem or Dash, or possibly even Ripple, although I imagine that would be more on the banking side of things. One currency eventually will be the currency of day to day transactions, it may not even exist yet today, but the one that does will incredibly valuable.
