Bitcoin is just a medium of exchange....The real wealth is contained within the goods and services which are exchanged utilizing the platform.  If one were to store all of their wealth into a cryptocurrency, instead of exchanging it for an equally valued good or service, and the market dropped out because it was stolen or exploited, then it would have no value to anybody.  In that case, another medium of exchange would present itself.  The goods (bricks, steel, gas, solar panels....etc) and the services (doctors, lawyers, engineers....etc) are where true wealth abides, not the means of exchanging such wealth.  Now....if a blockchain could become more resourceful and utilitarian, then we'd have a whole different beast for which to contend.  <---Just an observation!
