A cryptocurrency (or “crypto”) is a digital currency that can be used to buy products and services, but utilizes 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 costs skyward.

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

1. What is cryptocurrency?

Cryptocurrency is a form of payment that can be exchanged online for products and services. Numerous companies have released their own currencies, typically called tokens, and these can be traded specifically for the great or service that the company supplies. Consider them as you would arcade tokens or casino chips. You’ll require to exchange real currency for the cryptocurrency to access the great or service.

Cryptocurrencies work using an innovation called blockchain. Blockchain is a decentralized innovation spread throughout many computer systems that manages and tape-records deals. Part of the appeal of this technology is its security.

2. How many cryptocurrencies are there? What are they worth?

More than 6,700 various cryptocurrencies are traded publicly, according to CoinMarketCap.com, a market research website. And cryptocurrencies continue to proliferate, raising money through initial coin offerings, or ICOs.

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, presumably before they end up being more valuable Some supporters like the reality that cryptocurrency removes central banks from handling the cash supply, since with time these banks tend to reduce the value of money by means of inflation Other advocates like the innovation behind cryptocurrencies, the blockchain, since it’s a decentralized processing and recording system and can be more protected than standard payment systems Some speculators like cryptocurrencies since they’re increasing in value and have no interest in the currencies’ long-term approval as a method to move cash

4. Are cryptocurrencies an excellent investment?

Cryptocurrencies may go up in worth, however numerous financiers see them as mere speculations, not real investments. The reason? Much like genuine currencies, cryptocurrencies generate no capital, 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 financial investment. Contrast that to a well-managed company, which increases its worth with time by growing the profitability and capital of the operation.

For those who see cryptocurrencies such as bitcoin as the currency of the future, it should 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 noteworthy voices in the financial investment community have recommended potential financiers to steer clear of them. Of particular note, legendary investor Warren Buffett compared Bitcoin to paper checks: “It’s a very reliable method of transferring money and you can do it anonymously and all that. A check is a method of transmitting money too. Are checks worth a lot of cash? Even if they can send cash?” 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 so that merchants and consumers can identify what a fair cost is for products. 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 worth 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 produces a conundrum. If bitcoins might be worth a lot more in the future, individuals are less most likely to invest and flow them today, making them less practical as a currency. Why invest a bitcoin when it could be worth 3 times the worth next year?
