Merchants interested in accepting bitcoin should worry about the possibility that looming regulation could upend the system.

Given its volatility, security issues and legal concerns, merchants interested in accepting bitcoin have a lot to worry about, especially with the possibility (as some see it) that looming regulation could upend the entire system. To mitigate the risk and open merchants up to new revenue streams, startups such as BitPay and Coinvoice make it easier for companies to accept the cryptocurrency.

These payment processors act as middlemen: A shopper pays in bitcoin, but the merchant can decide whether to be paid in bitcoin, fiat currency, or a combination. This allows companies to shield themselves from the uncertainty of the currency or to dip a toe into accepting it as payment. Until bitcoin becomes more stable and regulated, payment processors such as these will be a safer option for merchants. (For more on bitcoin, see also our post on the Inside Bitcoins conference.)
