A cryptocurrency (or “crypto”) is a digital currency that can be utilized to purchase items and services, but uses an online journal with strong cryptography to protect online transactions. Much of the interest in these unregulated currencies is to trade for profit, with speculators sometimes driving rates skyward.

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

1. What is cryptocurrency?

Cryptocurrency is a kind of payment that can be exchanged online for items and services. Many companies have actually provided their own currencies, typically called tokens, and these can be traded specifically for the good or service that the business supplies. Think about them as you would arcade tokens or casino chips. You’ll need to exchange real currency for the cryptocurrency to access the good or service.

Cryptocurrencies work using an innovation called blockchain. Blockchain is a decentralized innovation spread throughout many computers that manages and tapes 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 different cryptocurrencies are traded publicly, according to CoinMarketCap.com, a marketing research website. And cryptocurrencies continue to proliferate, raising money through preliminary coin offerings, or ICOs. The total worth 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:

Advocates see cryptocurrencies such as Bitcoin as the currency of the future and are racing to buy them now, probably prior to they become better Some supporters like the truth that cryptocurrency gets rid of central banks from managing the cash supply, since over time these banks tend to minimize the value of money via inflation Other advocates like the technology behind cryptocurrencies, the blockchain, since it’s a decentralized processing and recording system and can be more safe than standard payment systems Some speculators like cryptocurrencies since they’re increasing in value and have no interest in the currencies’ long-term acceptance as a method to move money

4. Are cryptocurrencies a great financial investment?

Cryptocurrencies might increase in worth, but many financiers see them as simple speculations, not real financial investments. The factor? Much like real currencies, cryptocurrencies produce no cash flow, so for you to profit, someone has to pay more for the currency than you did.

That’s what’s called “the greater fool” theory of investment. Contrast that to a well-managed business, which increases its worth gradually by growing the profitability and capital of the operation.

For those who see cryptocurrencies such as bitcoin as the currency of the future, it needs to be kept in mind that a currency requires stability.” As NerdWallet writers have noted, cryptocurrencies such as Bitcoin might not be that safe, and some notable voices in the investment neighborhood have encouraged prospective investors to stay away from them. Of specific note, legendary financier Warren Buffett compared Bitcoin to paper checks: “It’s a very effective way of transferring cash and you can do it anonymously and all that. A check is a method of sending cash too. Are checks worth a lot of cash? Even if they can transmit money?” For those who see cryptocurrencies such as Bitcoin as the currency of the future, it ought to be kept in mind that a currency requires stability so that merchants and consumers can identify what a reasonable price is for items. Bitcoin and other cryptocurrencies have actually been anything but stable through much of their history. For instance, while Bitcoin traded at near $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 once again.

This rate volatility develops a quandary. If bitcoins might be worth a lot more in the future, people are less most likely to spend 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?
