What are cryptocurrencies?

In short, cryptocurrencies are digital, decentralized currencies (aka tokens) that use cryptography to secure transactions. You’ve probably heard of Bitcoin—it’s been in headlines for years now thanks to its meteoric rise (and subsequent fall). But there are many other cryptocurrencies that aren’t quite as well-known; they all differ in what they offer investors and users. What we’re looking at today are what are known as platform coins, which have their own protocols that developers can create apps for. These coins aim to provide solutions for different industries and fulfil specific niches — including Bitcoin, Ethereum, Ripple, Litecoin and more. As noted above, these four coins make up 79% of the total cryptocurrency market cap at present time.

How do they work?

Cryptocurrencies are essentially a digital form of money designed to be secure, durable, portable, anonymous and free from centralized control. (To learn more about cryptocurrency in general, check out our guide to Bitcoin.) Bitcoin is different from regular fiat currencies because it’s decentralized—there isn’t one bank or organization that controls its supply. Instead, transactions are processed by a network of computers known as miners. The value of these transactions in turn affects what bitcoins can buy you. One of the main reasons for crypto’s popularity is blockchain technology, which acts like a transparent public ledger with information such as transaction amounts visible to all parties. This makes cryptocurrencies difficult to hack or counterfeit—something many financial experts have worried would happen when electronic cash began gaining popularity 20 years ago.

Why do they matter?

Most experts believe that cryptocurrency will change finance forever. The global market value of cryptocurrencies today—$153 billion in total—is paltry compared with other financial assets. But even if cryptocurrencies have staying power, it may be a stretch to expect them to replace cash or credit cards anytime soon.

Are they secure?

Cryptocurrencies are based on encryption techniques that are supposed to ensure security. But like any other form of money, you can lose your cryptocurrency to theft, fraud or simply misplacing it. It’s also not as stable as a government-backed currency—which means its value fluctuates much more than traditional fiat currencies such as U.S. dollars or euros.
