As cryptocurrencies buzz louder, it’s easy to feel like you’ve missed it if you don’t invest in Bitcoin, Ethereum and other digital currencies. But personal finance expert Dave Ramsey didn't stop him when it comes to crypto publicity.

He said in a recent interview with the Shawn Ryan show that too many people were going all out before they could build a real financial foundation. That's not just adventure. “That’s stupid,” he said.

There are three things you should think about putting your money into encryption, Ramsey said.

Before gambling on cryptocurrencies, Ramsey stressed that priorities should ensure your retirement. This is first of all to contribute to your 401(k), especially if your employer offers a match. In fact, while 70% of Americans contributed 401(k), only 47% of Zers said they saved for retirement plans.

Too many people delay investing in retirement, which benefits digital assets. But Ramsey believes that cryptocurrencies are not investments at all. This is a guess. "What happens to people who own gold or cryptocurrencies...they are confused by the concept of speculation and investment," Ramsey said. "The only thing you can do in cryptocurrencies is speculate...the guess is a short-term game."

So if you are investing in cryptocurrencies but don't contribute to 401(k) and other retirement accounts, you may need to rethink.

Ramsey also stressed that not investing in mutual funds rather than using cryptocurrencies as a mistake. He suggests building a portfolio that grows over time, rather than just one based on hype-based value fluctuations.

"What Buffett (Warren) talks about is true. I want an investment that is creating wealth instead of changing prices," Ramsey explained. "When Home Depot stock goes up or Apple stock goes up, it's because they make a profit... it creates wealth. When cryptocurrencies go up or gold goes up, it's just because others want more. It doesn't create anything."

Ramsey also mentioned the mistake of not buying a home instead of buying cryptocurrency. For many Americans, home ownership is one of the most reliable ways to build wealth over time. According to Forbes, home ownership offers tax benefits and prevents inflation while allowing you to build equity.

"They aren't buying a house. Instead, they put 100% of what they have in the middle of a roulette, which is stupid. It's ridiculous."
