If the value of gold increased as rapidly as the value of bitcoin, and the value of all kind of "I pull a fictitious metal name out of the air and make it tradable" materials increased at a striking pace as well, we'd also say it reeks of scam, right?
How fast do you think would price of gold raise if it was discovered just decade ago even if it had no industrial applications but it was objectively limited in supply and total amount that will eventually get mined?
I think bit slower than bitcoin just because bitcoin is so easily splittable, transfersble and easy to hold safely.
