Since 1971, the US dollar has lost roughly 99% of its value against gold. The pound lost more. The euro, about the same. Pick a fiat currency, any fiat currency, and the chart is the same melting line.
Gold didn't get more valuable. The money got worse. 1971 is when the dollar's last tie to gold was cut, and the line has bled downhill every year since, because a currency that can be printed without limit will be printed without limit. That is not a conspiracy. It is an incentive.
Gold told the truth about that for fifty years, and almost nobody acted on it, because gold is hard to hold, hard to move, and easy for a government to call in. So people kept the melting money instead.
Bitcoin is gold's lesson with the friction removed. A hard cap of 21 million, held by you, moved by you, callable by no one. Same escape hatch, no vault, no permission, no exit anyone can close.
The dollar has been telling you what it is since 1971. The only question left is what you hold instead.
