-Lower inflation than gold; the hardest money for thousands of years (asymptotically approaches 0%)
-Predictable and stable inflation unlike fiat (market can price that in for any point in time you know how much Monero there will be) Easier to plan for the future. No one has unfair insider knowledge or cantillon effect advantage either)
-Every Monero requires expending energy to mine it (i.e. similar to mining gold) PoW just like Bitcoin. No one can arbitrarily print it out of thin air.
