Bitcoin is showing stamina as it outlasts other digital currencies.

In its fourth year of circulation now, the decentralized online-only form of money has evolved from a libertarian-styled geek curiosity to a contender for becoming the first digital currency to go truly mainstream. There are now more than 11 million “coins” created worth more than $1 billion. Lumpy and volatile as it is, the math-based cash is one of the fastest-rising alternative currencies in a world filled with them.

Tyler Moore, who studies alternative currencies, said he still isn’t sure why.

“It’s one part luck, one part decentralization, and one part this design that carries appeal for people that don’t like inflation,” said Moore, an assistant professor of computer science and engineering at Southern Methodist University in Dallas. “The timing of it was really good.”

Bitcoin slipped onto the scene in 2009, as trust in established banks crumbled and inflation fears rose. It’s not managed by anyone. There’s no central bank. It’s based on open-source encryption technology.

In fact, the digital cash can be created by anyone with the hefty computer power required to solve specified algorithms that secure the network. Bitcoins are rewards for effort. The system takes banks out of the picture completely as individuals pay each other directly. Transactions are private, but because there’s a public ledger of them, it’s unlikely they are perfectly anonymous.
