From beginner to advanced — master exchanges, wallets and blockchain essentials
A.M. Antonopoulos’ Mastering Bitcoin is a strong technical guide for readers who want to understand how Bitcoin actually works.
Bitcoin was introduced by the pseudonymous Satoshi Nakamoto to create peer-to-peer electronic cash without relying on a central intermediary.
Bitcoin was introduced by the pseudonymous Satoshi Nakamoto to build a peer-to-peer electronic cash system that does not rely on a single authority.
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.
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.
Not all bitcoins are truly owned or available. Some are unmined, some are held, and some are likely lost and no longer spendable.
