Much of the interest in these uncontrolled currencies is to trade for profit, with speculators sometimes driving prices 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 goods and services. Lots of companies have issued their own currencies, typically called tokens, and these can be traded particularly for the excellent or service that the business supplies.

3. Why are cryptocurrencies so popular?

Cryptocurrencies interest their advocates for a range of factors. Here are some of the most popular:

Fans see cryptocurrencies such as Bitcoin as the currency of the future and are racing to buy them now, probably before they become more valuable Some supporters like the truth that cryptocurrency gets rid of reserve banks from managing the money supply, since in time these banks tend to minimize the worth of cash via inflation Other fans like the innovation behind cryptocurrencies, the blockchain, since it’s a decentralized processing and recording system and can be more safe and secure than conventional payment systems Some speculators like cryptocurrencies due to the fact that they’re increasing in value and have no interest in the currencies’ long-lasting approval as a method to move cash

4. Are cryptocurrencies an excellent investment?

Cryptocurrencies might increase in worth, but many financiers see them as simple speculations, not real investments. The reason? Similar to genuine currencies, cryptocurrencies generate 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 higher fool” theory of investment. Contrast that to a well-managed company, which increases its value in 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 must be kept in mind that a currency requires stability.” As NerdWallet authors have kept in mind, cryptocurrencies such as Bitcoin might not be that safe, and some noteworthy voices in the investment neighborhood have recommended would-be financiers to steer clear of them. Of particular note, legendary investor Warren Buffett compared Bitcoin to paper checks: “It’s a really reliable way of transferring money and you can do it anonymously and all that. A check is a method of transferring money too. Are checks worth a great deal of cash? Even if they can transmit cash?” For those who see cryptocurrencies such as Bitcoin as the currency of the future, it must be noted that a currency requires stability so that merchants and consumers can identify what a fair cost is for goods. 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. By December 2020, it was trading at record levels once again.

This cost volatility develops 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 practical as a currency. Why invest a bitcoin when it could be worth three times the worth next year?
