Bitcoin (BTC)

Bitcoin (BTC) is the first and largest cryptocurrency by market capitalisation. It was introduced in 2009 by the pseudonymous Satoshi Nakamoto as a peer-to-peer electronic cash system that operates without a central authority. Unlike stablecoins such as USDT or USDC, Bitcoin’s value is not pegged to any fiat currency — it is determined entirely by market supply and demand. Bitcoin has a hard supply cap of 21 million coins, making it a deflationary asset by design.

Bitcoin on Noxpay

Noxpay supports Bitcoin on Mainnet:

​

Address formats

Bitcoin supports several address formats:

• Legacy (P2PKH): starts with 1 — the original format, supported everywhere.
• Script (P2SH): starts with 3 — used for multisig and SegWit-wrapped addresses.
• Native SegWit (Bech32): starts with bc1q — lower fees, not supported by all older wallets.
• Taproot (Bech32m): starts with bc1p — newest format, highest efficiency.

Noxpay supports all standard Bitcoin address formats. When in doubt, confirm with your recipient which format their wallet accepts.

​

Network uniqueness

Unlike EVM-compatible tokens, Bitcoin has a single mainnet. There is no cross-network ambiguity: a BTC withdrawal goes to Bitcoin Mainnet, and the address format is distinct from any other supported currency. There is no risk of sending to the wrong chain.
