A cryptocurrency (or “crypto”) is a digital currency that can be utilized to buy goods and services, but utilizes an online ledger with strong cryptography to protect online transactions. Much of the interest in these uncontrolled currencies is to trade for profit, with speculators at times driving costs skyward.

Here are seven things to ask about cryptocurrency, and what to keep an eye out for.

1. What is cryptocurrency?

Cryptocurrency is a type of payment that can be exchanged online for goods and services. Lots of companies have issued their own currencies, frequently called tokens, and these can be traded particularly for the excellent or service that the company provides. Think of them as you would arcade tokens or casino chips. You’ll need to exchange genuine currency for the cryptocurrency to access the good or service.

Cryptocurrencies work using an innovation called blockchain. Blockchain is a decentralized innovation spread across numerous computers that manages and tape-records deals. Part of the appeal of this innovation is its security.

2. How many cryptocurrencies are there? What are they worth?

More than 6,700 various cryptocurrencies are traded publicly, according to CoinMarketCap.com, a market research site. And cryptocurrencies continue to multiply, raising money through preliminary coin offerings, or ICOs. The overall value of all cryptocurrencies on Dec. 18, 2020, was more than $645.7 billion, according to CoinMarketCap, and the overall worth of all bitcoins, the most popular digital currency, was pegged at about $421.7 billion.

3. Why are cryptocurrencies so popular?

Cryptocurrencies appeal to their supporters for a variety of factors. Here are a few of the most popular:

Supporters see cryptocurrencies such as Bitcoin as the currency of the future and are racing to purchase them now, most likely before they become better Some fans like the reality that cryptocurrency gets rid of central banks from handling the cash supply, because over time these banks tend to lower the worth of cash by means of inflation Other fans like the innovation behind cryptocurrencies, the blockchain, since it’s a decentralized processing and recording system and can be more protected than standard payment systems Some speculators like cryptocurrencies because they’re increasing in worth and have no interest in the currencies’ long-lasting approval as a method to move cash

4. Are cryptocurrencies a great financial investment?

Cryptocurrencies may go up in value, but many financiers see them as simple speculations, not real investments. The factor? Much like genuine currencies, cryptocurrencies produce no cash flow, so for you to benefit, somebody has to pay more for the currency than you did.

That’s what’s called “the greater fool” theory of financial investment. Contrast that to a well-managed service, which increases its value over time by growing the success and capital of the operation.

For those who see cryptocurrencies such as bitcoin as the currency of the future, it must be kept in mind that a currency requires stability.” As NerdWallet authors have kept in mind, cryptocurrencies such as Bitcoin may not be that safe, and some notable voices in the financial investment neighborhood have recommended potential investors to avoid them. Of specific note, legendary investor Warren Buffett compared Bitcoin to paper checks: “It’s an extremely effective method of transmitting cash and you can do it anonymously and all that. A check is a method of sending money too. Are checks worth a great deal of cash? Even if they can transfer cash?” For those who see cryptocurrencies such as Bitcoin as the currency of the future, it should be noted that a currency needs stability so that merchants and consumers can identify what a fair price is for products. Bitcoin and other cryptocurrencies have been anything but stable through much of their history. For instance, while Bitcoin traded at close to $20,000 in December 2017, its value then dropped to as low as about $3,200 a year later on. By December 2020, it was trading at record levels again.

This price volatility creates a problem. If bitcoins might be worth a lot more in the future, people are less likely to invest and flow them today, making them less feasible as a currency. Why spend a bitcoin when it could be worth 3 times the value next year?
