The total supply of Bitcoin is capped at 21 million coins, but that does not mean all of them are in active circulation at once.
Yes. Bitcoin has a hard cap of 21 million coins. What matters is how that cap works, how issuance slows, and why scarcity is only part of pricing.
How is there a finite amount of bitcoin? The protocol sets a 21 million cap, fixed issuance rules, and halving events that slow new supply over time.
All bitcoins will not be mined anytime soon. Issuance keeps slowing after each halving, so the final stretch takes far longer than many expect.
When all bitcoins are issued, the network does not stop. Blocks still get mined, but miner revenue shifts from block subsidies to transaction fees.
If all bitcoins are bought, the network does not stop. The main effects are tighter supply, harder trading, and higher scam risk.
If all bitcoins are bought, trading does not end. The real effect is tighter supply, harder execution, wider spreads, and higher scam risk.
Bitcoin is often cited as one of the best-performing assets ever, but the answer depends on time frame, volatility, and how performance is measured.
