My point is that the best currencies DON'T have real-world use cases, or else they would be influenced by external supply & demand. For example, you don't store your wealth in crude oil because the demand has seasonality, and the supply depends on whatever the heck OPEC feels like doing. Too much volatility.
Gold was traditionally the hardest money because it doesn't have large industrial use. Additionally, it's extremely rare (when compared to copper, silver, etc.) so its supply is fairly stagnant. Those two factors are what has made it a reliable store of value, meaning not much fluctuation.
Bitcoin takes this to the next level. Lacking real-world use is a feature, not a bug, and means the supply is ONLY handled by the block reward rate, which has been set in stone since the first block was mined.
For a detailed explanation, read the Bitcoin Standard.
Gold was once "set in stone" at $35/oz after Roosevelt took a dump on the entire American people forcing them to sell all their gold at $25/oz. Then for no reason at all (not really ) the Americans decided the dollar was no longer gonna be backed by gold. But gold is still recognized as money around the entire world.
If the almighty Government decides Bitcoin is now illegal, what are you gonna do with your censored Comcast monopoly Internet-backed currency at Walmart when Walmart is not allowed to transact in Bitcoin? The cronies in the EU is now discussing banning Bitcoin because a digital currency needs to be "safe" and "protected". Agenda 2030 has only room for one digital currency and it will be centrally planned and backed by nothing but force.
Will you be able to VPN and Tor transact Bitcoin to your friendly potato-farming farmer because you want food and he really wants Bitcoin so that he can purchase a new tractor from the Bitcoin Black Market?
I understand gold can be confiscated and outlawed, but it's much harder to control and track under the Unification Board-dystopia fast approaching.
Does the Bitcoin Standard cover this?
