Cryptocurrency is now the best-preferred mode for financial exchanges over the internet. Despite various hurdles such as fluctuations, cryptocurrency provides the most secure means of exchange as it involves several encryptions. Most people like cryptocurrency because it’s anonymous since it’s decentralized (meaning no central bank controls your funds) and you can transact from one user to another without using intermediaries.
The most commonly used cryptocurrency is Bitcoin. Bitcoin uses blockchain technology – transactions are recorded in a public ledger and verified cryptographically by various nodes in the network. This blockchain technology makes it hard to steal or forge bitcoins as you have to hack all the nodes in the network which is an impossible task due to the encryptions involved.
除了涉及加密和安全问题外，您可能还听说过数百万加密货币在这里或那里被盗的头条新闻。这是在线交易所钱包和中枢的漏洞。由于黑客无法入侵区块链，他们就会利用这些交易所，从毫无戒心的用户那里窃取资金。加密货币中最好的东西也是最糟糕的东西--匿名性。一旦你的账户资金被盗，你就无法追踪。
加密货币的安全风险
加密货币的安全风险除了交易所容易受到攻击外，以下是与加密货币相关的一些安全风险；
- ICO fraud – Initial coin offering is a source of capital for cryptocurrency startups. This capital is in the form of other cryptocurrencies. At times, some deals might be fake and can result in loss of your funds.
- 假冒的交易交易所- 有些交易所就是为了盗取您的资金而建立的，因为您会随意提供资金。请务必确保您的交易所信誉良好。
- Hackable offline wallets – As much as you might want to avoid online, some offline wallets have been known to be hackable. Trojans such as Pony loader have been known to identify offline wallets and then steal from them.
- 加密劫持- 这种形式的安全风险涉及恶意行为者劫持您的设备并使用其资源（如 CPU）来挖掘加密货币。这会大大降低系统性能。这通常是通过恶意软件挖矿脚本完成的。
- Phishing attacks – Even cryptocurrencies are not immune to these old evolving attacks. According to Coin telegraph, a phishing attack on Electrum Wallet stole almost $1million worth cryptocurrency in one hour.
VPN 能否保护您防范加密货币安全风险？
VPN 能否保护您防范加密货币安全风险？A VPN can protect you against various cryptocurrency security risks but not all. Due to the strong encryptions involved, a VPN can help you against some phishing attacks and crypto jacking in which the mining malware is injected using free public Wi-Fi. A VPN will encrypt your internet traffic, and this will make it invisible to prying eyes, and hence it won’t be intercepted or susceptible to prying eyes.
A VPN can also help you carry out cryptocurrency transactions in areas where there’s heavy government surveillance. Besides the encryptions, a VPN assigns you a virtual IP address which masks your real IP and hence hides your location.
