This is exactly what I have been saying. If it is not a replacement, if you stay in the US$ economy, then you are just adding an layer of activity, but accomplishing nothing substantive. And, all of the risks of piracy, counterfeits, padding of accounts by hackers (or miners) is still right there alongside your disdain for the US$. I wish you well, but this is just not for me.
You don’t see anything “substantive,” but others seem to value what the technology accomplishes. I value improved security relative to other electronic transaction mechanisms, merchants value reduced costs relative to the same. We’ll see where is goes.
