Bitcoin (BTC) Supply Cap Does Not Prevent Losses Above 70%

Bitcoin (BTC) has a hard issuance ceiling of 21 million coins, but that limit does not shield the market from deep losses, making scarcity an incomplete measure of how much risk buyers face.

The cap governs how many BTC the protocol will create; it does not set the market price. Bitcoin’s price depends on supply and demand, so the issuance limit cannot by itself show whether the asset is attractively priced or guarantee that its value will rise.

New supply enters through mining rewards, which are reduced by half every 210,000 blocks, an interval of roughly four years. Bitcoin’s fourth halving took place Apr. 20, 2024, at block 840,000, cutting the block subsidy to 3.125 BTC. The next reduction is estimated for 2028, at block 1,050,000, when the subsidy would fall to 1.5625 BTC. The protocol sets the trigger by block count, so the calendar date remains an estimate.

That slower issuance has not prevented severe price declines. Peak-to-trough losses in earlier Bitcoin market cycles regularly exceeded 70% to 80%. In the cycle that began in 2022, the decline from a record high had not exceeded about 50% as of Feb. 8, 2026. That figure is tied to that cutoff and does not describe what happened after it.

The percentages matter because losses and gains apply to different balances. A 70% decline would reduce a $10,000 position to $3,000, a $7,000 loss. To return from $3,000 to $10,000, it would need to gain about $7,000, or roughly 233% of its reduced value.

The example shows why a percentage recovery must be larger than the percentage loss: after the decline, the starting balance is much smaller. A drawdown is a peak-to-trough decline, while a recovery calculation measures the increase from the lower amount. The two percentages answer different questions about the same price move.

Bitcoin’s supply cap describes the pace and eventual limit of issuance, while historical drawdowns show that market prices can fall far below their peaks. Neither measure can say whether Bitcoin will gain or lose value in a future cycle.

The next estimated halving in 2028 is expected to reduce the per-block subsidy again, but it will not change the cap’s role as an issuance rule.
