Not sure what a seed phrase is?

Did you know? 🤔

There are three main types of crypto wallets: Custodial – Your funds are held and managed by an exchange or third party. Non-Custodial Hot – You control the wallet, and it’s connected to the internet. Non-Custodial Cold – You control the wallet using an offline hardware device.

Did you know? 🤔

Every Bitcoin address in your wallet is generated from the same set of 12 (or sometimes 24) random words, known as your seed phrase. ⚠️ That’s why it’s important to keep your seed phrase safe and offline. Anyone with access to it has complete control of your crypto.

How Different Systems Approve Transactions

Traditional finance and Bitcoin approve transactions very differently. Visa relies on private servers controlled by one company, concentrating trust. Banks depend on policies, regulators, and legal frameworks, with customers trusting institutions to act fairly. Bitcoin instead uses open-source code and consensus, where every node verifies transactions. The result is a system without central control—transparent and resistant to manipulation.

Why Fiat Money Loses Value Over Time

Traditional money (fiat) loses value over time due to inflation, as governments and central banks can print more, reducing purchasing power. In contrast, assets like land, art, and Bitcoin are scarce – land can’t be created, rare art has cultural value, and Bitcoin has a fixed supply of 21 million. This scarcity helps them preserve or even grow in value long term.

Understanding Wallet Types

Not all wallets are equal. Hot wallets are online — convenient but more exposed. Cold wallets stay offline — safer but less convenient. Wallets can also be custodial (third party holds keys) or non-custodial (you hold them). As the saying goes: ‘Not your keys, not your coins.’ With Xverse, you can choose between the ease of a hot wallet or enhance your security by connecting a hardware device to make it cold.

Why Bitcoin Earned the Title “Digital Gold”

Bitcoin is often called digital gold because it shares the key property that made gold valuable for thousands of years: scarcity. Only 21 million bitcoins will ever exist, and that cap cannot be inflated or altered without consensus across the entire network. Unlike gold, which is heavy to move and difficult to divide, Bitcoin can be transferred instantly across borders and divided into 100 million satoshis per coin, making it far more practical in the digital age. These qualities give Bitcoin its reputation as a modern, programmable form of gold.

Earning Yield with BitcoinFi in Xverse

With Xverse, Bitcoin holders can go beyond just holding and access BitcoinFi. Stack STX to earn BTC rewards, use BOB to borrow stable assets, or tap Lombard for extra yield strategies —all while keeping exposure to your holdings. As a non-custodial wallet, Xverse keeps your funds in your hands, secured by your keys. The result: flexibility — your Bitcoin can earn yield, provide liquidity, or serve as collateral. 👉 Explore at portfolio.xverse.app/earn/btc-staking

What Permissionless Money Really Means

Bitcoin is often called permissionless money because it removes the need for banks, governments, or corporations to approve your transactions. With only a private key, you have full control of your funds and can send or receive money at any time — no banking hours, no borders, no gatekeepers. This empowers individuals with true financial sovereignty, making it possible for anyone, anywhere in the world, to participate in the global economy freely and without asking for permission.

Buying Bitcoin in Xverse

Xverse makes it simple to buy Bitcoin directly from the app — no need to move between multiple platforms. All you need to do is open the app, tap “Buy,” choose a provider, enter how much you want, and complete your payment. Once the transaction is confirmed, your Bitcoin is deposited straight into your non-custodial wallet, meaning only you control the keys. It’s one of the easiest and most secure ways to get started with Bitcoin.

Runes: Tokens on Bitcoin

The Runes protocol enables fungible tokens natively on Bitcoin, without sidechains or external blockchains. Designed to work seamlessly within Bitcoin’s infrastructure, Runes let developers and communities launch tokens, build apps, and experiment with Bitcoin-based assets. This expands the ecosystem, bringing innovation that once lived on other chains back to Bitcoin—while keeping security anchored to its base layer. With Xverse, you can easily explore Runes and swap tokens securely at portfolio.xverse.app/swap

Why Bitcoin Needs Layer 2s

Bitcoin is the most secure and decentralized foundation in crypto, but it was not designed for high-speed payments or complex applications. That’s where Layer 2 networks come in. They build on top of Bitcoin to make transactions faster, cheaper, and more flexible, while unlocking features like smart contracts and scalable apps. This lets Bitcoin go beyond “digital gold” and become the base layer for a new financial ecosystem.

Why Bitcoin Earned the Title “Digital Gold”

Bitcoin is often called digital gold because it shares the key property that made gold valuable for thousands of years: scarcity. Only 21 million bitcoins will ever exist, and that cap cannot be inflated or altered without consensus across the entire network. Unlike gold, which is heavy to move and difficult to divide, Bitcoin can be transferred instantly across borders and divided into 100 million satoshis per coin, making it far more practical in the digital age. These qualities give Bitcoin its reputation as a modern, programmable form of gold.

Why Test Transactions Matter

When sending Bitcoin for the first time, it’s always best to start small. Addresses are long strings of characters, and a single mistake can send funds to the wrong place permanently. By sending a small test amount first, you can confirm that the address is correct and the transfer works as expected. Once it’s confirmed, you can safely send the larger amount, protecting yourself from costly errors. With Xverse, you can also save trusted addresses in your personal address book, giving you quick and secure access every time you need to send Bitcoin.

Spotting and Avoiding Scams

No legitimate wallet provider or support team will ever ask for your 12-word recovery phrase. Scammers often pose as “support” and use urgency to pressure you into giving it away. The right response is to ignore the message and report the account. Never share your seed phrase under any circumstances — once someone else has it, they have complete control over your funds. For official help from Xverse, visit support.xverse.app, where you’ll find helpful articles and the option to open a ticket with our team.

The Importance of Bitcoin’s Fixed Supply

One of Bitcoin’s most revolutionary features is its fixed supply of 21 million coins — unlike fiat money, which governments can print without limit. New issuance is predictable, halving about every four years, with the final fraction mined around 2140. This built-in scarcity makes Bitcoin increasingly harder to obtain over time and underpins its role as a store of value.

Why Mining Is Essential to Bitcoin

Mining plays a central role in keeping Bitcoin alive and secure. By solving complex mathematical puzzles, miners compete to add new blocks of transactions to the blockchain. When they succeed, they are rewarded with newly created bitcoins and transaction fees. This does two things at once: it brings new coins into circulation and ensures that every transaction is permanently recorded in the public ledger. Mining is what prevents fraud, secures the history of the network, and replaces the need for a central authority to oversee money.

The First Cryptocurrency

Bitcoin is the world's first cryptocurrency, launched on the 3rd of Janurary in 2009 by the anonymous creator Satoshi Nakamoto. It introduced blockchain technology, which allows for secure peer-to-peer transactions without needing a bank or central authority. Bitcoin's creation kickstarted the entire digital currency market.

The Right Way to Add Bitcoin to Your Wallet

The safest ways to get Bitcoin into your wallet are to buy it directly through an on-ramp service (like using a credit card in Xverse) or to receive it from another wallet on-chain. If anyone ever asks you to share your 12-word recovery phrase to get free coins or an “airdrop,” it’s a scam. The only way to fund your wallet is by making a purchase or receiving a transfer — never by giving away your keys.

Protecting Your Seed Phrase

Your 12-word seed phrase is the master key to your wallet. Anyone who has it can access your funds, no matter where they are in the world. Screenshots, cloud storage, or messaging apps leave it exposed to hackers and malware. The most secure action is to write it down on paper or engrave it on metal and store it in a safe, offline place. This ensures that you keep full control of your Bitcoin while minimizing the risk of theft.

Ordinals: Unlocking Bitcoin for Art and Culture

Ordinals let users inscribe digital content onto individual satoshis, Bitcoin’s smallest unit, turning them into unique digital collectibles. This innovation brought NFTs to Bitcoin, enabling creators to secure their work on the world’s most robust blockchain. By embedding culture into Bitcoin, Ordinals expanded it from ‘just money’ into a platform for art, identity, and expression. Xverse was the first mobile wallet to support Ordinals, making it easy for anyone to explore this new frontier.

How Layer 2s Extend Bitcoin’s Capabilities

Bitcoin’s base chain is intentionally simple to remain secure. Layer 2s allow developers to add smart contract capabilities without altering Bitcoin’s core design. This creates a safe balance: the base layer stays immutable and reliable, while L2s experiment with new features and user experiences. This is how Bitcoin evolves without sacrificing its original mission of security and decentralization.

Different Layer 2s, Different Strengths

Not all Bitcoin Layer 2s serve the same purpose. Lightning is built for private, fast, and low-fee payments. Stacks focuses on smart contracts and earning BTC yield through stacking. Spark enables instant low-cost transfers with a native Bitcoin asset. And Starknet brings cryptographic proofs for scale and speed. Each Layer 2 adds a different toolset, giving Bitcoin users more ways to interact with the network beyond simple transactions.

Why Leaving Bitcoin on Exchanges is Risky

Buying Bitcoin on an exchange is just the first step. If you leave it there, you don’t truly own it. The exchange controls the private keys, which means you are trusting them to stay solvent, secure, and honest. History has shown that exchanges can fail, get hacked, or freeze withdrawals without warning. To fully own your Bitcoin, you need to transfer it into a non-custodial wallet like Xverse, where you control the keys and therefore the funds.

How Different Systems Approve Transactions

Traditional finance and Bitcoin approve transactions very differently. Visa relies on private servers controlled by one company, concentrating trust. Banks depend on policies, regulators, and legal frameworks, with customers trusting institutions to act fairly. Bitcoin instead uses open-source code and consensus, where every node verifies transactions. The result is a system without central control—transparent and resistant to manipulation.

The Rise of BitcoinFi

BitcoinFi, short for Bitcoin Finance, puts Bitcoin to work beyond holding. With Layer 2s and new protocols, you can lend, borrow, trade, and earn yield. Unlike traditional finance, it’s open and permissionless — anyone with internet can join. Instead of banks, users interact with smart contracts and decentralized pools, secured by Bitcoin. This lets holders unlock liquidity without selling, earn passive BTC rewards, and access global financial tools 24/7 on the world’s most secure blockchain.
