4. Are cryptocurrencies a good financial investment?

Cryptocurrencies might increase in value, but numerous investors see them as mere speculations, not real financial investments. The reason? Just like genuine currencies, cryptocurrencies produce no cash flow, so for you to benefit, someone 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 organization, which increases its worth over 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 ought to be kept in mind that a currency requires stability.” As NerdWallet writers have kept in mind, cryptocurrencies such as Bitcoin may not be that safe, and some noteworthy voices in the financial investment neighborhood have actually encouraged prospective investors to stay away from them. Of particular note, famous investor Warren Buffett compared Bitcoin to paper checks: “It’s a really effective way of transmitting money and you can do it anonymously and all that. A check is a method of sending cash too. Are checks worth a lot of cash? 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 customers can identify what a reasonable rate is for goods. Bitcoin and other cryptocurrencies have been anything however stable through much of their history. For instance, while Bitcoin traded at close 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 again.

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