4. Are cryptocurrencies a great investment?

Cryptocurrencies might increase in worth, but lots of financiers see them as simple speculations, not real financial investments. The reason? Similar to real currencies, cryptocurrencies create no cash flow, so for you to benefit, someone has 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 service, which increases its value gradually 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 ought to be kept in mind that a currency needs stability.” As NerdWallet authors have noted, cryptocurrencies such as Bitcoin may not be that safe, and some notable voices in the investment neighborhood have advised potential financiers to steer clear of them. Of particular note, legendary financier Warren Buffett compared Bitcoin to paper checks: “It’s an extremely efficient way of transferring cash and you can do it anonymously and all that. A check is a way of transmitting money too. Are checks worth a lot of money? Even if they can transmit 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 identify what a fair price is for products. Bitcoin and other cryptocurrencies have been anything but stable through much of their history. For instance, 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 on. By December 2020, it was trading at record levels once again.

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