A third of your money, silently taken. The US Dollar lost 39.1% over just 20 years. No vote. No consent. No receipt. The inflation tax is invisible, until you measure it. Bitcoin is the exit.

The Great Divergence
Your currency's purchasing power vs. Bitcoin, on a logarithmic scale. This is the only honest way to show both on the same chart.
Logarithmic scale: each gridline represents a 10x change. This is how you compare an asset that lost 24% with one that gained 2,350%.
The US Dollar lost 23.6% of its purchasing power. In the same window, Bitcoin appreciated +2,350%. On a linear chart, the fiat line would be invisible, a rounding error next to Bitcoin's growth. The log scale lets you see both, and the divergence is the story of our monetary era.
