什麼是比特幣 (BTC) 及其工作原理？初學者指南

自 2009 年由神秘的中本聰開發以來，比特幣已成為加密貨幣和金融科技領域的基礎。

Bitcoin, introduced in 2009 by the enigmatic Satoshi Nakamoto, has become a cornerstone of the cryptocurrency and fintech landscape. As the first decentralized cryptocurrency, Bitcoin has spurred immense growth in blockchain technology, becoming the most visible and widely adopted coin in the market. Facilitating seamless transactions on the blockchain, Bitcoin has been adopted as legal tender in some countries and is used globally for a diverse range of applications.

比特幣由神秘的中本聰於 2009 年推出，現已成為加密貨幣和金融科技領域的基石。作為第一個去中心化的加密貨幣，比特幣刺激了區塊鏈技術的巨大成長，成為市場上最引人注目和廣泛採用的貨幣。比特幣促進了區塊鏈上的無縫交易，已在一些國家被採用為法定貨幣，並在全球範圍內用於各種應用。

Currently, Bitcoin is utilized by people worldwide for various services. Notably, Bitcoin has been adopted not only as legal currency in El Salvador but also for every day transactions—for instance, trading a pizza from Papa John’s or depositing funds at online casinos and sports betting websites.

目前，比特幣被世界各地的人們用於各種服務。值得注意的是，比特幣不僅在薩爾瓦多被採用為法定貨幣，而且還被用於日常交易——例如，交易棒約翰披薩或在線上賭場和體育博彩網站存入資金。

Bitcoin's value lies in its enhanced privacy, cryptographic security, and the development of encrypted wallets that ensure safe transactions on a global scale. Let’s dive into how Bitcoin works, how to use it, and the best ways to keep it secure:

比特幣的價值在於其增強的隱私性、加密安全性以及確保全球範圍內安全交易的加密錢包的開發。讓我們深入了解比特幣的工作原理、使用方法以及確保其安全的最佳方法：

What is Bitcoin (BTC) & How Does it Work?

什麼是比特幣 (BTC) 及其工作原理？

Despite being around for over a decade, newcomers may still wonder, “what is bitcoin?” In simple terms, Bitcoin is a decentralized digital currency that operates independently of any central bank. Instead of relying on a traditional financial institution, Bitcoin transactions are verified by networked computers through a process known as mining, which involves solving complex mathematical problems. Once mined, Bitcoin can be transferred directly to others or used for purchases with bitcoin-accepting vendors, with each transaction being recorded on a public ledger—the blockchain.

儘管比特幣已經存在十多年了，但新手可能仍然想知道“比特幣是什麼？”簡單來說，比特幣是一種去中心化的數位貨幣，獨立於任何中央銀行運作。比特幣交易不依賴傳統的金融機構，而是由聯網電腦透過稱為「挖礦」的過程進行驗證，該過程涉及解決複雜的數學問題。一旦開採出來，比特幣就可以直接轉移給其他人，或用於向接受比特幣的供應商購買，每筆交易都記錄在公共分類帳（區塊鏈）上。

This decentralized, peer-to-peer system ensures that all Bitcoin transactions are transparent yet pseudonymous. Even though each transaction is publicly available on the blockchain, the identities of the transacting parties can remain concealed.

這種去中心化的點對點系統確保所有比特幣交易都是透明且匿名的。儘管每筆交易都是在區塊鏈上公開的，但交易方的身份仍然可以被隱藏。

How to Use Bitcoin Online

如何在線使用比特幣

Before first buying and using bitcoin, you will need to set up a wallet in which to store it. Here's a simple guide to start using Bitcoin:

在首次購買和使用比特幣之前，您需要設定一個錢包來儲存它。這是開始使用比特幣的簡單指南：

Set Up a Wallet: Choose a secure Bitcoin wallet for your needs. You’ll need both a public key (like an account number) for receiving funds and a private key (like a password) for authorizing transactions. Many hot wallets and cold wallets are available, each with its pros and cons for different users.

設定錢包：選擇適合您需求的安全比特幣錢包。您需要用於接收資金的公鑰（如帳號）和用於授權交易的私鑰（如密碼）。有許多熱錢包和冷錢包可供選擇，每種錢包對於不同的用戶來說都有其優缺點。

Find Vendors that Accept Bitcoin: Many online services and products now accept Bitcoin, although some may only accept other cryptocurrencies. Once you’ve found a vendor, you can use your wallet to send Bitcoin directly for goods or services.

尋找接受比特幣的供應商：許多線上服務和產品現在都接受比特幣，儘管有些可能只接受其他加密貨幣。找到供應商後，您可以使用錢包直接發送比特幣購買商品或服務。

Send Bitcoin to Other Users: Bitcoin transfers are similar to traditional bank transfers, though they remain independent of banks. Ask the recipient for their wallet address, then transfer funds directly to their wallet.

將比特幣發送給其他用戶：比特幣轉帳與傳統銀行轉帳類似，但仍獨立於銀行。詢問收款人的錢包地址，然後將資金直接轉入他們的錢包。

How to Store Bitcoin Safely

如何安全儲存比特幣

When using Bitcoin, securing your funds is critical. Here are key wallet types and best practices for safe Bitcoin storage:

使用比特幣時，保護您的資金至關重要。以下是安全比特幣儲存的關鍵錢包類型和最佳實踐：

Hot Wallets: These are digital wallets connected to the internet, such as mobile or web apps. Hot wallets are convenient for frequent transactions but are more vulnerable to cyber threats. When using hot wallets, consider diversifying to reduce risk.

熱錢包：這些是連接到網路的數位錢包，例如行動或網路應用程式。熱錢包方便頻繁交易，但更容易受到網路威脅。使用熱錢包時，請考慮多樣化以降低風險。

Cold Wallets: Cold wallets, like hardware wallets, are offline storage solutions, ideal for long-term holdings. These wallets are disconnected from the internet, making them less accessible to potential hackers. While they’re more secure, they can be less convenient for immediate transactions.

冷錢包：冷錢包與硬體錢包一樣，是離線儲存解決方案，非常適合長期持有。這些錢包與互聯網斷開連接，因此潛在的駭客更難訪問它們。雖然它們更安全，但即時交易可能不太方便。

Seed Phrases and Private Keys: When you set up a wallet, you’ll often receive a seed phrase—a recovery phrase that enables you to restore your funds if you lose access to your wallet. It’s essential to keep both your seed phrase and private key secure and offline. The public key can be shared with anyone for receiving Bitcoin, but the private key must remain private to ensure the safety of your funds.

種子短語和私鑰：當您設定錢包時，您通常會收到種子短語，這是一種恢復短語，可讓您在無法存取錢包時恢復資金。確保助記詞和私鑰的安全和離線狀態至關重要。公鑰可以與任何人共享以接收比特幣，但私鑰必須保持私密，以確保您的資金安全。
