Crypto Basics: Blockchain, Wallets, and Your First Transfer

What you will learn

Cryptocurrency introduces a new set of words, but the first useful distinction is simple: the network records transfers, while a wallet helps you access and use your assets. This guide explains how those pieces fit together.

Blockchain, assets, and wallets

A blockchain is a shared record maintained by a network. In Bitcoin, participants check transactions against common rules, and confirmed transactions become part of the chain's history. A wallet uses cryptographic keys to authorize spending; coins are not physical files stored inside the wallet. A receiving address tells a sender where to direct a transfer. Learn how Bitcoin works.

An address can be shared to receive supported assets. A private key or recovery phrase must remain secret because it can provide control over funds. These are different from an account password. Never type a recovery phrase into a support chat or a link sent by a stranger.

Custodial and self-custody accounts

With a custodial service, the provider manages the keys and records your account balance. With self-custody, you manage the keys yourself. Neither arrangement removes risk: an account can be compromised, a provider can fail, and a lost self-custody recovery phrase can make funds inaccessible. Understand who controls the keys and how recovery works before using a wallet.

A transfer has more than one detail

Before moving an asset, compare the asset name, receiving address, blockchain network, and any required memo or tag. An identical token symbol does not mean every network is supported. Check the receiving platform's instructions, minimum deposit, fees, and confirmation requirements. OrangeX's deposit guide explains selecting the token and network.

For example, if a receiving screen names one specific network, do not choose a different network merely because its fee looks lower. First establish that the sending and receiving sides support the same route. If a test transfer is appropriate, it must still meet the destination's minimum requirements.

Price and technology are separate questions

Understanding how a network works does not tell you what its asset will be worth. A functional blockchain can still have a volatile token price. Before evaluating any asset, write down three separate questions: What does it do? How can I store and transfer it? What could cause me to lose money?

Quick knowledge check

• Is a receiving address the same as a recovery phrase? No.
• Does a familiar ticker guarantee the correct network? No.
• Does understanding the technology guarantee a return? No.

Start with these distinctions before exploring orders, leverage, or more complex products. This article is educational and is not a recommendation to buy or sell any asset.
