Leander, Cedar Park businesses now accept Bitcoin currency as payment

"It's the freest form of currency," he said. "Over a lifetime of transaction fees, a business has to absorb that or it ends up getting passed along to the customer."

However, Kerr said, one of the biggest benefits is that his dental services are more accessible to customers who may need to use Bitcoin.

"As a dentist, my No. 1 goal is to make people's teeth healthier," he said. "By accepting Bitcoin, we are removing a barrier to care, especially for someone who knows they need a lot of treatment. Maybe their only financial avenue is Bitcoin because they got it when it was relatively cheap."

When first introduced, each Bitcoin was worth pennies. However, the exchange rate in early 2014 floated around $800 per Bitcoin, according to the website www.bitcoinexchangerate.org.

Steven Wilkinson, founder of Austin Bitcoin, has helped Kerr and other local merchants such as La Canasta Meat Market and Hill Country Home Improvements in Leander set up Bitpay, one of several payment systems designed to transfer Bitcoin and exchange it into dollars. Though critics of Bitcoin call it unpredictable and unstable, Wilkinson said the system gives more financial freedom to merchants.

"There is going to be some volatility with something that new, but it's getting to be less of an issue as more people become involved in the network," Wilkinson said. "I saw businesses having smaller and smaller margins of profitability. With Bitcoin, we keep more money local so we don't have to pay a fee to go through a bank."

Danny Sessoms, owner of Hill Country Home Improvements, said he hopes more local merchants will begin using Bitcoin. Sessoms said he specifically seeks out vendors who accept Bitcoin using www.coinmap.com, and in January, he purchased beer at La Canasta Meat Market using the currency.
