什么是数字货币？
( R$ J7 g4 g% A$ v$ X( i1 l数字货币在许多方面都类似于传统货币，但使用一种独特的在线数据库(称作区块链)来存储所有的交易记录。 这些记录的完整性通过先进的加密技术得到保护，数字货币也因此而得名。除了比特币作为第一大数字货币之外，还有上千种其他类型的数字货币在交易平台被自由交易。6 K# k" k6 b7 ?/ j* v g* }
5 s0 s2 H; o7 A5 d1 R
数字货币怎么买?" Z" S4 [ k$ D0 m/ Q
大多可使用信用卡及其他支付方式购买数字货币，也可以运用其他的数字货币交易工具。通常买入数字货币需要您创建钱包和管理私钥，让您在数字货币交易平台买入数字货币会更加灵活，只要购买数字货币，平台就会将您购入的数字货币自动划入您的钱包啦。% d# g8 l% A a- `( o# c: E. n
/ L T. F0 G4 l0 D; `为什么要购买数字货币？7 B2 t# g* Y; u6 o
通常，人们出于各种目的买入数字货币，如价值存储、交换媒介、或者用于交易或质押等。买什么数字货币能赚钱呢？虽然目前数字货币，尤其是比特币(BTC)和以太坊(ETH)已经逐渐受到机构投资者的认可，数字货币总体上仍然是一种波动大、有风险的资产类型。
0 X' D {' S& |
7 ]8 \( W' Q' m: I1 `2 @7 W# t4 m6 V购买数字货币安全吗？
; z. H9 ]0 E; R( z" N4 A数字货币不受中央机构或银行的干预，只有通过私钥访问地址才能使用这些资产，因此妥善保管私钥以保证资金安全就显得格外重要。这也意味着任何拥有私钥的人就拥有了这些数字资产的使用权，可以将其自由支配和转移。当您购买数字货币时，我们建议您选择安全的交易所，顶级的安全基础架构和防风险体系可以为您的交易和资产安全保驾护航。
# H, a# @$ n7 h5 h7 G- _, g: e% o1 F+ T9 \& k5 L, p! M
数字货币的用途是什么？0 d4 Q/ G9 C; R. l9 t
数字货币有很多种用途和应用场景。例如，比特币(BTC)可以用于价值存贮和交换媒介，以太坊(ETH)则有其他应用场景，支持虚拟机运行和智能合约的执行等。
