The comparing the 3d Print with a cryptos hummm may be a reference but its a tecnologi emerging and change so true about the cryptos but 3dPrinting are not on actions or wallstreet its just a product, mean while the cryptos manage the money and reference to money, and 3d printing no make money but make funy things :D and can make stuff that can make money with that ...!!!

but the reference that the 3dPrinting emerge in a time the peopple say what is that.. ? and now make amaizing things with they.. soo in a future no far away o more close that we imagine im sure the cryoptos convert in a more than a virtual coins .. and more and more we use in our dairy life..

So i like the analogy of them...!!!
well done My frind a nice post!!!
