The maximum Bitcoin supply is 21 million coins. That cap helps explain scarcity, but it does not mean all coins are in circulation or available to buy.
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.
There is no single fixed answer to what percent of Americans own Bitcoin. The result depends on survey methods, timing, and how “own” is defined.
Amazon usually does not sell Bitcoin directly. The real issue is spotting gift-card routes, off-platform deals, and scams before you pay.
Usually no. Binance does not generally list Amazon gift cards as a standard way to buy bitcoin, so check payment options and fraud risks first.
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, trading does not end. The real effect is tighter supply, harder execution, wider spreads, and higher scam risk.
