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

Here are seven things to ask about cryptocurrency, and what to watch out for.

1. What is cryptocurrency?

Cryptocurrency is a form of payment that can be exchanged online for products and services. Many companies have provided their own currencies, often called tokens, and these can be traded specifically for the good or service that the company supplies. Consider 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 utilizing an innovation called blockchain. Blockchain is a decentralized technology spread across lots of computer systems that manages and tape-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 various cryptocurrencies are traded publicly, according to CoinMarketCap.com, a marketing 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 attract their supporters for a variety of reasons. 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 more valuable Some supporters like the reality that cryptocurrency gets rid of reserve banks from managing the cash supply, given that over time these banks tend to lower the value of cash through inflation Other supporters like the innovation 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 because they’re going up 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 might go up in value, but lots of financiers see them as mere speculations, not real financial investments. The factor? Much like real currencies, cryptocurrencies create no capital, so for you to profit, somebody has to pay more for the currency than you did.

That’s what’s called “the higher fool” theory of investment. Contrast that to a well-managed organization, which increases its worth with time by growing the profitability and cash flow 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 needs stability.” As NerdWallet authors have actually kept in mind, cryptocurrencies such as Bitcoin might not be that safe, and some notable voices in the investment community have actually recommended would-be financiers to avoid them. Of specific note, legendary financier Warren Buffett compared Bitcoin to paper checks: “It’s a very efficient method of transferring money and you can do it anonymously and all that. A check is a method of sending money too. Are checks worth a whole lot of cash? Even if they can send money?” For those who see cryptocurrencies such as Bitcoin as the currency of the future, it ought to be noted that a currency needs stability so that merchants and consumers can identify what a fair rate is for items. Bitcoin and other cryptocurrencies have actually been anything but stable through much of their history. For example, while Bitcoin traded at near to $20,000 in December 2017, its worth then dropped to as low as about $3,200 a year later. By December 2020, it was trading at record levels again.

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