Bitcoin and gold share similarities as stores of value, but Bitcoin’s fixed supply of 21 million coins means each BTC represents a much larger slice of its total supply compared to a troy ounce of gold in its vast 7 billion-ounce stockpile, leading to Bitcoin’s higher volatility since big trades move more of the overall pie. As Bitcoin’s price climbs, say, to $1 million per coin, trading shifts to satoshis, its tiniest units (100 million per BTC), allowing everyday investors to buy affordable fractions like $100 worth, which spreads ownership beyond big holders and dampens price swings, much like gold’s stability after ditching the gold standard in 1971. This dynamic highlights Bitcoin’s undervaluation: its $2.1 trillion market cap is just a fraction of gold’s $28.8 trillion, suggesting massive growth potential as adoption grows and volatility eases.
