This story is a little bit old, but Capital One has confirmed that currently they decline all credit card purchases of cryptocurrency. Capital One also made the following statement to breitbart:
Capital One is currently declining credit card transactions to purchase cryptocurrency due to the limited mainstream acceptance and the elevated risks of fraud, loss, and volatility inherent in the cryptocurrency market.
 Capital One continues to closely monitor developments in cryptocurrency markets and exchanges and will regularly evaluate the decision as cryptocurrency markets evolve.
I’m already dreading the comments section on this post. Remember you can disagree with each other without the name calling. Keep it civil and respectful.
