4. Are cryptocurrencies a good investment?

Cryptocurrencies may increase in worth, but lots of 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 profit, 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 service, which increases its value 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 should be kept in mind that a currency needs stability.” As NerdWallet authors have kept in mind, cryptocurrencies such as Bitcoin might not be that safe, and some noteworthy voices in the financial investment community have actually advised prospective financiers to avoid them.

Bitcoin and other cryptocurrencies have actually been anything but stable through much of their history.

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