While the number of businesses and stores that accept Bitcoin payments is increasing with each passing month, the ability to freely spend digital currency in everyday life is still restricted. To combat this obstacle, a number of companies have offered Visa or MasterCard debit cards linked to a digital currency wallet to allow conversion to fiat money on the fly. This allows you to spend digital currency as you would any fiat currency, or use ATMs to withdraw cash.
However, a significant issue has been the restriction on availability, since these cards cannot currently be shipped to US addresses. Efforts to resolve that obstacle are presently underway, and may offer at least a partial solution to that limitation.
