01 / THE NETWORK

Digital value, verified by a network.

Bitcoin is a peer-to-peer system in which participating computers apply shared rules to transactions. A private key authorizes spending. Confirmed transactions become part of a public ledger.

Mining places transactions into blocks using proof of work. A payment appearing in a wallet and a payment receiving confirmations are different stages. Confirmation times vary; no fixed settlement time is promised.

Simplified conceptual sequence. This site never asks for a wallet connection, private key or recovery phrase.

02 / THE UNITS

You do not need a whole bitcoin.

One bitcoin (BTC) is divided into 100,000,000 satoshis (sats). Bitcoin's current consensus rules limit total issuance to approximately 21 million BTC. A supply limit does not establish a market price or guarantee purchasing power.

03 / CUSTODY

Who can authorize a transaction?

Custody is about control of signing keys and recovery arrangements. Compare responsibilities before choosing a service or a wallet.

ArrangementControlQuestions to ask
Third-party custodyA provider controls spending keys.How are assets held? Can withdrawals be suspended? What happens if the provider fails?
Self-custodyYou control the required keys.How will you protect backups, verify addresses and recover access?
MultisignatureA threshold of keys authorizes spending.Who holds each key? Can the threshold still be met after a loss or provider failure?

A 2-of-3 setup can tolerate one unavailable key if two valid signing keys and the required wallet information remain available. Its usefulness depends on implementation and recovery procedures.

04 / ORGANISATIONAL READINESS

Start with governance.

A business considering Bitcoin needs a documented purpose, spending authority, liquidity policy, custody plan and accounting process. Its board and qualified advisers must evaluate its own legal and tax obligations.

  • Define acceptable exposure and stress-test a severe price decline.
  • Separate authorization, transaction preparation and verification.
  • Document recovery and succession; rehearse without exposing secrets.
  • Verify jurisdiction, provider eligibility, fees and reporting requirements.
