But what is it? And what should you watch out for?
Some stores in New York City are accepting cryptocurrency as payment, and there are Bitcoin ATMs throughout the area that turns cash into crypto.
At Astro West on the Upper West Side, they sell everything from unique stones to fossils to ancient meteorites. And customers can now pay for the oldest objects with the newest form of currency.
"You have to keep changing and adapting or you're going to have a 'closed' sign on your door," owner Marc Tanjeloff said. "I remember at one point we were writing checks and using American Express sliders. It's just the future, it's changing."

Unlike cash, crypto is an internet based currency. Bitcoin is the older form of cryptocurrency.
There's no single person or organization in charge, so instead of banks processing the transactions, computers do the work for you.

He says there are three main areas of concern to keep in mind.

"My advice would be, as a lawyer, don't get adventurous," Dilendorf said.
