Digital currencies like Bitcoin have become todays hot topic as people make millions off their meteoric rise in value. Digital currencies allow us to trade with anyone in the world. Its like spending cash directly from our owncomputers. In theory, there are no banking fees and no worries about identity theft. You have privacy, and your money is protected from any governments inflating currency. When Bitcoin came out, most of us didnt buy any. We didnt get involved. And we missed the significance of this technology. But are there profits still to be made?
