The largest cryptocurrency, bitcoin, is a commodity and not a payment system, according to Visa’s chief executive. Visa will also not give bitcoin or other cryptocurrencies a platform for wire transfers and exchanges. “I don't view it as payment system player,” CEO Alfred Kelly told CNBC.

“We at Visa won't process transactions that are cryptocurrency-based. We will only process fiat currency-based transactions,” he added. Visa is the world's largest credit card company.

Bitcoin was originally created as an alternative de-centralized currency. However, with its 2,000 percent growth last year, it has become a source for speculators to make a quick buck. As bitcoin turnover grows, it faces problems like high fees, astoundingly slow transactions and volatile prices.
