Much of the interest in these unregulated currencies is to trade for profit, with speculators at times driving prices skyward.

Here are 7 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. Lots of companies have provided their own currencies, typically called tokens, and these can be traded particularly for the good or service that the company supplies. Consider them as you would arcade tokens or gambling establishment chips. You’ll need to exchange genuine currency for the cryptocurrency to access the good or service.

3. Why are cryptocurrencies so popular?

Advocates see cryptocurrencies such as Bitcoin as the currency of the future and are racing to purchase them now, probably prior to they become more valuable Some supporters like the reality that cryptocurrency removes central banks from managing the money supply, given that over time these banks tend to reduce the value of cash through inflation Other advocates like the technology 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 because they’re increasing in worth and have no interest in the currencies’ long-term acceptance as a method to move money

4. Are cryptocurrencies a great investment?

Cryptocurrencies might go up in value, but lots of investors see them as mere speculations, not real financial investments. The reason? Just like real currencies, cryptocurrencies generate no capital, so for you to profit, somebody needs to pay more for the currency than you did.

That’s what’s called “the higher fool” theory of financial investment. Contrast that to a well-managed business, which increases its worth gradually by growing the success 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 needs stability.” As NerdWallet authors have kept in mind, cryptocurrencies such as Bitcoin may not be that safe, and some noteworthy voices in the financial investment community have actually encouraged prospective financiers to avoid them. Of specific note, legendary financier Warren Buffett compared Bitcoin to paper checks: “It’s a very effective way of transferring money and you can do it anonymously and all that. A check is a way of transferring money too. Are checks worth a great deal of money? Even if they can transmit money?” 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 so that merchants and customers can determine what a fair cost is for items. Bitcoin and other cryptocurrencies have actually been anything however stable through much of their history. For example, while Bitcoin traded at near 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 again.

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