NEW YORK -- It is the hottest currency in the world: the. In the past 12 months, investors have driven the value up nearly 1,500 percent. There are true believers, and others who warn the bitcoin bubble could burst.
At a New York City bar, the drinks are flowing -- and so is the conversation about bitcoin. "I think bitcoin is the future of currency," one patron said.
"What it promised was a money that could exist outside of the control of Wall Street and outside the control of any government," said New York Times reporter Nathaniel Popper.
So what is bitcoin? It isn't money you can hold in your hand. Some consider it the new gold -- a digital currency that exists online. You can buy and sell them on a bitcoin exchange.

"You are the youngest bitcoin millionaire. How does that feel?" CBS News asked Finman. "It feels pretty great, not too bad for 19," he said.
At age 12, Finman invested a $1,000 gift from his grandma.
"I check the bitcoin price every 30 minutes," he said. "I get a notification on my phone, every 30 minutes I check the bitcoin price."
Despite its recent popularity, we are not yet at the point where bitcoin is widely used in day-to-day transactions. And as enticing as it may be, investing in bitcoin is not for everyone. A good rule of thumb: if you can't stomach a volatile market, it's best to take it really slow.
