Cryptocurrency is a form of digital money that uses computer code to make transactions secure. It’s decentralized, which means that no one person or organization controls it. In addition, it’s fungible — meaning you can swap it for other currencies and get the same value.
It’s also untraceable, which can be useful for criminals. Government agencies can still track the financial activity of people who use crypto, however.
The blockchain is a network of computers that record the details of every transaction in real time, making it impossible to falsify. It also allows for secure transactions between two parties without the need for a third party, such as a bank or credit card company.
In addition, crypto offers a variety of other advantages over traditional currencies, such as portability and divisibility. It’s also resistant to inflation and requires no central intermediary, which reduces the risk of a single point of failure.
It can be used for a wide range of activities, from making payments to buying goods and services online. There are even cryptocurrencies that allow you to pay for non-cash remittances, such as mobile data top-ups or utility bills.
You can buy cryptocurrencies through a cryptocurrency exchange, which is a kind of stock broker that allows you to trade the various digital assets. Some exchanges have higher fees than others, so be sure to compare them before you invest in any.
The most popular digital asset platform is ethereum, which is built atop the blockchain and allows developers to create smart contracts. Users can then use the ethereum platform to swap, trade or purchase other digital assets.
New cryptocurrencies are created through something called “mining.” Miners use computers to solve difficult mathematical puzzles, and the first one to win gets to add their coin to the blockchain. It’s possible to use a computer or smartphone to mine cryptocurrencies, but it generally requires more powerful hardware. It can also use a lot of electricity, so it’s important to consider your power usage when selecting the best miner for you.
A great way to ensure that your cryptocurrency investment is protected is to use a secure exchange that protects your information. The most secure ones require two-factor identification, which means you’ll receive a text message or email with a unique code to verify your identity before you can sign up.
You’ll also want to choose an exchange that accepts bank account transfers, as these tend to have the lowest fees. It’s also a good idea to spread your investments across several different types of cryptocurrencies.
If you’re looking to trade cryptocurrencies, make sure that you have the proper tools and know-how to do so. It’s also a good idea for you to have access to an attorney or financial advisor who can help you understand the risks and rewards of trading.
It’s important to keep in mind that cryptocurrencies are volatile, so you should limit them to a small portion of your overall portfolio. They’re also relatively high-risk investments, so it’s best to spread your money out and focus on long-term results.
