Fake talking points, especially "lack of portability". What do all outrageous scams have in common? They ALL have unrivaled portability, whether it's mortgage backed securities or fiat paper represented by digital numbers. Why do instruments like that have high portability? Because you aren't actually transferring ANYTHING of value at all. For all you elementary children out there, if something has no value, this is represented by the number zero. Transferring zero from point A to point B is a completely frictionless enterprise. It breaks no laws of physics!
You're attempting to claim something having absolutely no value whatsoever is a positive. Completely laughable. If something has abnormally high portability, it's not a sign you've discovered the holy grail, you've discovered the holy grail of scams. Friction is required in any real biological or cosmological process. As for difficulty to secure, how often do you see a silver or gold vault whether commerical or private being robbed or having everything in it mysteriously vanish? Not very often. How often do you see this in bitcoin? Like every day.
These are all complete bullshit, nonsensical talking points. "Difficulty to verify purity"? You obviously don't understand shitcoins have no Schelling point. You're the one with the "difficulty to verify" problem. Shitcoins can be produced infinitely with no overhead with absolutely no reason to use one over another. In fact, they have a reverse Schelling point because you're incentivized to use a different coin where the distribution favors you instead. Since you can't frictionlessly produce a new form of the noble metals in your basement, metals don't have show stopper problems like this.
