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

Here are seven things to inquire 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. Lots of business have actually provided their own currencies, frequently called tokens, and these can be traded particularly for the excellent or service that the company provides. Think about them as you would arcade tokens or casino chips. You’ll need to exchange real currency for the cryptocurrency to access the great or service.

Cryptocurrencies work utilizing a technology called blockchain. Blockchain is a decentralized technology spread across numerous computer systems that manages and records transactions. Part of the appeal of this innovation is its security.

2. The number of cryptocurrencies exist? What are they worth?

More than 6,700 different cryptocurrencies are traded openly, according to CoinMarketCap.com, a market research site. And cryptocurrencies continue to multiply, raising money through initial coin offerings, or ICOs. The total value of all cryptocurrencies on Dec. 18, 2020, was more than $645.7 billion, according to CoinMarketCap, and the overall value 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 fans for a variety of reasons. Here are some of the most popular:

Advocates see cryptocurrencies such as Bitcoin as the currency of the future and are racing to buy them now, probably before they end up being more valuable Some fans like the truth that cryptocurrency eliminates central banks from managing the cash supply, given that in time these banks tend to decrease the worth of cash 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 conventional payment systems Some speculators like cryptocurrencies due to the fact that they’re going up in value and have no interest in the currencies’ long-term acceptance as a way to move money

4. Are cryptocurrencies an excellent financial investment?

Cryptocurrencies may increase in worth, but lots of investors see them as mere speculations, not real financial investments. The reason? Similar to real currencies, cryptocurrencies create no cash flow, so for you to profit, somebody 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 service, which increases its worth with 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 ought to be noted that a currency requires stability.” As NerdWallet authors have kept in mind, cryptocurrencies such as Bitcoin might not be that safe, and some significant voices in the investment community have encouraged potential investors to avoid them. Of specific note, famous investor Warren Buffett compared Bitcoin to paper checks: “It’s a very effective method of transmitting money and you can do it anonymously and all that. A check is a way of transmitting cash too. Are checks worth a whole lot of money? Even if they can transmit money?” For those who see cryptocurrencies such as Bitcoin as the currency of the future, it needs to be noted that a currency needs stability so that merchants and consumers can identify what a fair rate is for products. Bitcoin and other cryptocurrencies have been anything but stable through much of their history. 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 develops a quandary. If bitcoins might be worth a lot more in the future, individuals are less most likely to spend and flow them today, making them less practical as a currency. Why spend a bitcoin when it could be worth three times the worth next year?
