Cryptocurrencies might go up in value, but numerous financiers see them as simple speculations, not real financial investments. The reason? Much like real currencies, cryptocurrencies produce no cash flow, so for you to benefit, somebody 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 with 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 needs stability.” As NerdWallet authors have noted, cryptocurrencies such as Bitcoin may not be that safe, and some notable voices in the investment community have encouraged potential investors to stay away from them. Of particular note, famous financier Warren Buffett compared Bitcoin to paper checks: “It’s an extremely efficient way of transmitting money and you can do it anonymously and all that. A check is a way of transferring cash too. Are checks worth a lot of money? Even if they can send money?” For those who see cryptocurrencies such as Bitcoin as the currency of the future, it must be noted that a currency requires stability so that merchants and consumers can identify what a fair cost is for goods. Bitcoin and other cryptocurrencies have actually been anything however stable through much of their history. For instance, while Bitcoin traded at near $20,000 in December 2017, its value 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 develops a dilemma. If bitcoins might be worth a lot more in the future, individuals are less most likely to invest and circulate them today, making them less feasible as a currency. Why spend a bitcoin when it could be worth 3 times the worth next year?
