Bitcoin learning guide
Published by Crypto Dispensers · 10 min read
Instead of being issued by a central bank, it runs on open-source software and a global network of independent computers. That network keeps a shared public record called the blockchain, which shows how value moves from one address to another.
The simple idea is this: Bitcoin lets people hold and transfer value using predictable rules that anyone can verify. To understand the full system behind it, read our complete guide on how Bitcoin works.
Bitcoin names both an open payment network and its asset, usually written BTC. The network lets participants check transfers using shared rules. BTC is the quantity people buy, receive or send.
Buying BTC does not give you shares in a Bitcoin company or in Crypto Dispensers. Bitcoin Cash, wrapped tokens and other cryptocurrencies are separate assets with their own rules. Check the asset and network named in an offer.
You can own a fraction of a Bitcoin. One BTC is divided into 100 million satoshis, often called sats. See the BTC and sats examples.
Bitcoin’s current rules limit total issuance to 21 million BTC. Full nodes, the computers independently checking the rules, reject blocks that create more than allowed. Miners cannot change that limit for nodes that keep enforcing it.
Confirmed transfers are recorded on a public blockchain, a history of transactions grouped into linked blocks. The record does not simply show everyone’s legal name. Public activity can still become linked to a person.
With self-custody, you manage the keys used to authorize spending. A provider can instead hold keys for you and show an account balance. These arrangements have different recovery and withdrawal conditions.
People use Bitcoin because it gives them a way to hold and move value through an open network. It is not tied to one bank, one app, or one country.
Some people use Bitcoin as a long-term store of value because its supply is limited and its rules are not controlled by a central bank.
Bitcoin can be sent across borders using wallet addresses instead of traditional bank rails, card networks, or money transfer services.
With self-custody, users can control Bitcoin through their own wallet keys instead of leaving access entirely with a third-party platform.
People can buy Bitcoin using different payment methods, including debit cards, bank transfers, and other supported options.
Important: Bitcoin can be useful, but it also carries risk. Prices can move quickly, transactions are final, and users should understand wallet safety before buying. For safety basics, read our guide on how to buy Bitcoin safely.
The blockchain records confirmed Bitcoin transactions in blocks linked to earlier blocks. Before inclusion, a transaction can be visible as unconfirmed. Broadcasting a payment does not guarantee it will be included.
Independent nodes check the blocks they accept. Proof of work makes replacing accepted history costly, and more confirmations generally reduce the chance of a reversal through a competing chain. There is no ordinary bank-style cancellation process.
Digital signatures show that spending was authorized by the required keys. Nodes check transactions and blocks against the rules. Miners compete to propose blocks through proof of work.
These checks do not establish that an invoice is genuine, that a recipient is honest or that Bitcoin’s price will rise. Protecting a wallet, choosing a provider and deciding how much risk to take are separate responsibilities.
A Bitcoin wallet is the tool that lets you receive, store, and send Bitcoin. It does not physically hold coins. It controls the keys that give access to Bitcoin recorded on the blockchain.
Your wallet address is where Bitcoin can be sent. It works like a receiving destination for Bitcoin transactions.
Private keys are what control the Bitcoin. If someone controls the keys, they control the ability to move the Bitcoin.
Self-custody means you control your wallet keys instead of leaving access entirely with an exchange or third-party platform.
When you send Bitcoin, your wallet creates a transaction and signs it. The network then verifies and records it.
In simple terms: Your wallet is how you access and control Bitcoin. The wallet address receives Bitcoin, and the private key controls it. For a deeper beginner explanation, read our Bitcoin wallet guide.
For a new Crypto Dispensers purchase, compare the wire, ACH, debit and credit options available to your account. Each has its own provider requirements, costs and timing. See the current buying options.
First establish whether your order includes delivery to a confirmed receiving wallet or credits an account that needs a later withdrawal. A successful payment does not prove both purchase and delivery are complete.
Retail cash loading and in-store cash deposits are discontinued. If you need help with an earlier cash payment, keep your receipt and contact official support.
The provider records your BTC balance. Sending it to another wallet may need a separate withdrawal, supported destination, fee and wait.
The sender broadcasts an on-chain transaction to the confirmed receiving address. Check its Bitcoin transaction ID, the matching amount and confirmations. A wallet may show it as pending before confirmation.
Who controls later spending depends on the keys for the receiving wallet. Compare wallet control and recovery before choosing where to receive Bitcoin.
A network fee pays for including an on-chain transaction in a block. Purchase charges and bank or card charges pay for different services. Check what is included in your quote so you do not count the same cost twice.
A transaction gets its first confirmation when included in a block. Later blocks increase the count. Receiving services set their own requirements, and the next block has no guaranteed arrival time.
Understand the fee categories or see how confirmations are counted.
No. BTC can be divided into satoshis. Check your provider’s purchase and withdrawal minimums and the full cost for your amount.
No. BTC is the asset of the Bitcoin network. Other assets and payment networks can have different rules and receiving instructions.
Yes. Limited supply does not guarantee demand, a stable dollar price or a profit. Consider the possibility of a loss before buying.
No. Read the guides and try the learning-path examples without opening an account or moving money.
