Sound #money requires a fixed supply, and is immune to debasement by any governing authority. This crucial aspect preserves your future purchasing power. As demand for sound money increases, its fixed supply ensures price appreciation over time. In contrast, unsound money, in other words #fiat loses value due to expansionary monetary policy by central planners, eroding its purchasing power. #Bitcoin is the only asset in existence with a hard cap on supply. It is the embodiment of absolute scarcity and is therefore the soundest of all money.
