97% of the US dollar's purchasing power has been erased since the Federal Reserve opened in 1913, per Bureau of Labor Statistics CPI-U data: a 1913 dollar buys roughly three cents today, or about $33 to $34 in 2026 equivalent. That figure compounds across 113 years of monetary history, through the Great Inflation of the 1970s, the end of gold convertibility in 1971, and the 2021-23 price spike. Bitcoin ($BTC), built around a fixed 21 million-coin supply as a direct counter to open-ended currency issuance, trades near $79,852 in early September 2026.
The 1971 break from gold convertibility removed the last hard anchor on monetary expansion and visibly steepened the dollar's decline. Before it, the erosion was measurable but bounded. After it, idle cash paid a continuous inflation tax with no ceiling in sight, and savers who held dollars across decades absorbed the full compounding loss.

Protocol vs. price record
Bitcoin's architecture answers the debasement argument directly: a 21 million-coin hard cap, a declining issuance schedule, no central issuer. The design is fixed by protocol. The price is not. Since the 2009 launch, $BTC has gained more than 59,000%, but that return has included single-cycle drawdowns of 50% to 80%. Early buyers saw purchasing power compound sharply; later buyers in the same cycles absorbed major losses. The comparison to the dollar is also not one-for-one: Bitcoin did not exist until 2009, so a 113-year side-by-side is impossible. Over full market cycles, it has outperformed cash and often gold on total return; inside any single cycle, the range of outcomes is wide.
ETF inflows and the institutional channel
The spot ETF approval in the United States in 2024 converted a bearer asset into a ticker. Pensions, registered investment advisers, and balance-sheet allocators can now hold Bitcoin exposure without managing private keys, and they have: $55.62 billion in cumulative net inflows through September 4, per SoSoValue, with $101.25 billion in total net assets, equal to 6.33% of Bitcoin's entire market cap.
Volatility stays elevated and regulation varies across jurisdictions. Custody and energy risks are unresolved. The dollar still clears most global trade, prices most debts, and anchors most wages. Bitcoin has not replaced it as a unit of account. The case it makes is narrower: since 2009, it has compounded faster than cash and often gold over full market cycles, measured against a currency that the Bureau of Labor Statistics says has lost 97% of its 1913 purchasing power.
