Some things you need to know
If you are about to explore Bitcoin, there are a few things you should know. Bitcoin lets you exchange money in a different way than with usual banks. As such, you should take time to inform yourself before using Bitcoin for any serious transaction. Bitcoin should be treated with the same care as your regular wallet, or even more in some cases!
Securing your wallet
Like in real life, your wallet must be secured. Bitcoin makes it possible to transfer value anywhere in a very easy way and it allows you to be in control of your money. Such great features also come with great security concerns. At the same time, Bitcoin can provide very high levels of security if used correctly. Always remember that it is your responsibility to adopt good practices in order to protect your money. Read more about securing your wallet.
Bitcoin price is volatile
The price of a bitcoin can unpredictably increase or decrease over a short period of time due to its young economy, novel nature, and sometimes illiquid markets. Consequently, keeping your savings with Bitcoin is not recommended at this point. Bitcoin should be seen like a high risk asset, and you should never store money that you cannot afford to lose with Bitcoin. If you receive payments with Bitcoin, many service providers can convert them to your local currency.
Bitcoin payments are irreversible
Any transaction issued with Bitcoin cannot be reversed, they can only be refunded by the person receiving the funds. That means you should take care to do business with people and organizations you know and trust, or who have an established reputation. For their part, businesses need to keep control of the payment requests they are displaying to their customers. Bitcoin can detect typos and usually won't let you send money to an invalid address by mistake. Additional services might exist in the future to provide more choice and protection for the consumer.
Bitcoin is not anonymous
Some effort is required to protect your privacy with Bitcoin. All Bitcoin transactions are stored publicly and permanently on the network, which means anyone can see the balance and transactions of any Bitcoin address. However, the identity of the user behind an address remains unknown until information is revealed during a purchase or in other circumstances. This is one reason why Bitcoin addresses should only be used once. Always remember that it is your responsibility to adopt good practices in order to protect your privacy. Read more about protecting your privacy.
Instant transactions are less secure
A Bitcoin transaction is usually deployed within a few seconds and begins to be confirmed in the following 10 minutes. During that time, a transaction can be considered authentic but still reversible. Dishonest users could try to cheat. If you can't wait for a confirmation, asking for a small transaction fee or using a detection system for unsafe transactions can increase security. For larger amounts like 1000 US$, it makes sense to wait for 6 confirmations or more. Each confirmationexponentially decreases the risk of a reversed transaction.
Bitcoin is still experimental
Bitcoin is an experimental new currency that is in active development. Although it becomes less experimental as usage grows, you should keep in mind that Bitcoin is a new invention that is exploring ideas that have never been attempted before. As such, its future cannot be predicted by anyone.
Don't forget government taxes
Bitcoin is not an official currency. That said, most jurisdictions still require you to pay income, sales, payroll, and capital gains taxes on anything that has value, including bitcoins.

你需要了解的一些事
如果你正打算探索比特币，有几件事需要先了解一下。比特币让你可以用不同于银行的方式交换资金。所以，在任何正式的交易之前花点时间告诉自己。要像爱护你的常规钱包一样爱护比特币。有些情况下，比特币甚至需要你投入更多的爱护。
保护你的钱包
和在现实生活中一样，你必须保护好自己的钱包。使用比特币可以轻而易举地在世界范围内转移资金，也让你完全掌控自己的资金。这样强大的功能也带来了很大的安全顾虑。同时，只要正确使用，比特币可以提供高级别的安全性。请随时牢记，你有责任采取良好的做法来保护自己的财产。了解更多关于保护钱包的内容。
比特币的价格多变
新兴的经济体，新奇的特性，有时候市场流动性的不足，导致比特币的价格可能在不可预知的情况下短时间内大起大落。所以，目前不建议用比特币来保存你的积蓄。比特币应该被视为高风险资产，千万不要将你无法承担损失的资金以比特币的形式保存。当别人用比特币付款给你时，有很多服务提供商可以让你将比特币立即转换为当地货币。
比特币交易是不可逆的
任何比特币交易一旦发生就无法逆转，只能是由收款人退回款项。也就是说你交易时要注意，要与自己了解和信任的个人或组织交易。不过不用担心，比特币系统可以检测出打字错误，通常不会让你付款到一个无效的地址。
比特币并不是匿名的
要花一些工夫才能在使用比特币时保护隐私。所有的比特币交易都公开且永久地存储在网络中，这就意味着任何人都可以查看到任何一个比特币地址中的余额和交易记录。除非比特币持有者在交易时透露了个人信息，比特币地址不会关联到比特币持有者的真实身份。这也就是为什么建议比特币持有者使用多个比特币地址的原因；事实上，你每次都应创建新的地址用于接收比特币。这在公共场合（比如在网站上）使用比特币时尤其重要。另外，你也可以考虑使用像Tor这样的工具来隐藏你的IP地址，使其不被记录。
即时交易相比没那么安全
比特币交易通常都会在几秒钟内发出，并且在10分钟内得到确认。在那段时间里，这笔交易被视为真实的，但仍可逆转。不诚实的用户可能试图欺骗。如果你真的等不及1个确认，要求对方支付一笔小额的手续费以加速交易确认，或使用一个不安全交易检测系统能够增加安全系数。对于金额较大的交易，比如达到1000美元，等待6个及6个以上的确认是有道理的。每增加一个确认，交易逆转的风险就会成指数级地降低。
比特币仍有实验性
比特币是一个正处于积极发展中的实验性新货币。尽管它的实验性正随着它不断增长的使用率而在逐渐减小，但是要记住比特币是一个全新的发明，它正探索以往从未被尝试过的理念，因此，没有人可以预测比特币的未来。
政府税收
比特币不是正式的货币。也就是说，大部分司法机构仍要求你对任何具有价值的所得交纳所得税，营业税，工资税和资本收益税，这其中也包括比特币。
