Much of the interest in these unregulated currencies is to trade for profit, with speculators sometimes driving costs skyward.

Here are 7 things to ask about cryptocurrency, and what to look out for.

1. What is cryptocurrency?

Cryptocurrency is a kind of payment that can be exchanged online for goods and services. Many companies have issued their own currencies, frequently called tokens, and these can be traded particularly for the excellent or service that the business provides. Think about them as you would arcade tokens or casino chips. You’ll require to exchange genuine currency for the cryptocurrency to access the excellent or service.

3. Why are cryptocurrencies so popular?

Cryptocurrencies attract their fans for a variety of factors. Here are some 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 become more valuable Some advocates like the fact that cryptocurrency eliminates central banks from managing the money supply, given that in time these banks tend to minimize the value of cash via inflation Other supporters like the technology behind cryptocurrencies, the blockchain, due to the fact that it’s a decentralized processing and recording system and can be more protected than traditional payment systems Some speculators like cryptocurrencies because they’re increasing in value and have no interest in the currencies’ long-term acceptance as a method to move cash

4. Are cryptocurrencies a good investment?

Cryptocurrencies might increase in value, but numerous investors see them as simple speculations, not real financial investments. The factor? Just like real currencies, cryptocurrencies create no cash flow, so for you to profit, someone needs 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 business, which increases its worth in time by growing the success and cash flow of the operation.

For those who see cryptocurrencies such as bitcoin as the currency of the future, it must 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 notable voices in the financial investment neighborhood have encouraged would-be investors to steer clear of them. Of particular note, legendary investor Warren Buffett compared Bitcoin to paper checks: “It’s an extremely reliable way of transmitting cash and you can do it anonymously and all that. A check is a method of transferring cash too. Are checks worth a whole lot of money? Just because they can transfer money?” 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 so that merchants and consumers can determine what a reasonable price is for goods. Bitcoin and other cryptocurrencies have been anything however stable through much of their history. For instance, 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 rate volatility creates a dilemma. If bitcoins might be worth a lot more in the future, individuals are less likely to spend and flow them today, making them less feasible as a currency. Why spend a bitcoin when it could be worth three times the worth next year?
