Bitcoin is a decentralized digital currency and payment network. This guide explains what it is, how it works, and what people often get wrong.

Bitcoin was introduced by the pseudonymous Satoshi Nakamoto to build a peer-to-peer electronic cash system that does not rely on a central authority.

When 21 million bitcoins are mined, new BTC issuance stops, but the Bitcoin network keeps running as miners rely more on transaction fees.

No. All 21 million bitcoins have not been mined yet. This guide explains how new BTC enters circulation, who can mine, and what costs matter.

The 20 millionth bitcoin is not tied to a fixed calendar moment. It depends on when block rewards push total issuance past that threshold.

How many bits are in a bitcoin? It depends on what “bits” means: a computing bit has no fixed conversion, while 1 BTC = 1,000,000 bits.

“A Wilson bitcoin” usually points to a person, brand, or piece of content tied to Bitcoin, not a separate coin. Context matters before trust does.

Wrapped Bitcoin (WBTC) is a token tied to Bitcoin’s value so BTC can be used on other blockchains, but it is not native Bitcoin.
