You may know Bitcoin is a controversial digital currency that makes news for falling or rising -- a lot. Less widely known is that consumers can acquire the cryptocurrency through ATMs, just like regular cash.
The number of machines installed worldwide is nearing 1,600, with the biggest hunk in the U.S. at more than 900, according to Coin ATM Radar, which tracks the information globally. That's up from virtually none at the beginning of 2014.
Bitcoin is available at all 1,567 cryptocurrency ATMs, followed by Litecoin, available at 357, according to Coin ATM Radar. Coinsource operates 128 ATMs in the U.S., making it the biggest, with machines across the country including New York, Philadelphia, and cities in Texas and California.
