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!
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.
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.
Any transaction you issue with Bitcoin cannot be reversed, it can only be refunded by the person receiving the funds. That means you should take care to do business with people or organizations you know and trust. But don't worry, Bitcoin can detect typos and usually won't let you send money to an invalid address.
Some effort is required in order 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 responsability to adopt good practices in order to protect your privacy.
A Bitcoin transaction is usually deployed within a few seconds and confirmed within 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 confirmation exponentially decreases the risk of a reversed transaction.
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.
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 Bitcoin.
