PayPal now lets shops accept Bitcoin

Bitcoin is an Internet-based system of money specifically designed to cut out middlemen, like banks and governments. So, it sounds odd to have Bitcoin processors. But they make it easier for everyday, non-tech-savvy businesses to accept bitcoins -- and immediately convert them to cash.

But why take bitcoins -- which have fluctuated in price from $1,100 and $400 in the last year -- instead of proven government money?

The system offers much lower transaction fees, which cost businesses a huge amount of money. The 2 percent to 3 percent that shops pay in credit card swiping fees can obliterate their profits.

Consider this PayPal's first -- but not last -- foray into the world of Bitcoin. The company has made clear that its interest in Bitcoin runs more than skin deep.
