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

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

1. What is cryptocurrency?

Cryptocurrency is a type of payment that can be exchanged online for items and services. Many companies have actually provided their own currencies, typically called tokens, and these can be traded particularly for the excellent or service that the company offers. Think of them as you would arcade tokens or casino chips. You’ll require to exchange real currency for the cryptocurrency to access the excellent or service.

Cryptocurrencies work using an innovation called blockchain. Blockchain is a decentralized technology spread across numerous computers that manages and tapes 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 openly, according to CoinMarketCap.com, a marketing research site. And cryptocurrencies continue to multiply, raising money through preliminary coin offerings, or ICOs.

3. Why are cryptocurrencies so popular?

Cryptocurrencies appeal to their advocates for a range of reasons. 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, presumably prior to they end up being more valuable Some supporters like the reality that cryptocurrency gets rid of central banks from managing the cash supply, because gradually these banks tend to lower the worth of money via inflation Other fans like the technology behind cryptocurrencies, the blockchain, due to the fact that it’s a decentralized processing and recording system and can be more safe than conventional payment systems Some speculators like cryptocurrencies since they’re going up in value and have no interest in the currencies’ long-term approval as a method to move money

4. Are cryptocurrencies an excellent investment?

Cryptocurrencies may go up in worth, but many investors see them as simple speculations, not real investments. The factor? Similar to real currencies, cryptocurrencies create no capital, so for you to benefit, someone needs 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 gradually 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 should be kept in mind that a currency needs stability.” As NerdWallet writers have actually noted, cryptocurrencies such as Bitcoin may not be that safe, and some notable voices in the financial investment community have actually recommended potential financiers to avoid them. Of particular note, famous financier Warren Buffett compared Bitcoin to paper checks: “It’s a very reliable method of sending cash 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? Just because they can transmit cash?” 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 customers can identify what a reasonable price is for products. Bitcoin and other cryptocurrencies have actually been anything however stable through much of their history. For example, while Bitcoin traded at close to $20,000 in December 2017, its worth then dropped to as low as about $3,200 a year later on. By December 2020, it was trading at record levels again.

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