Crypto-currencies

Crypto-currencies are digital online currencies that exhibit that use cryptographic algorithms to control the supply to create "virtual scarcity" and to overcome the counterfeiting and double spending problems. The first was Bitcoin, and then many more began to arise with their own unique properties, strengths and weaknesses such as Litecoin and Namecoin. Crypto-trading is now becoming very popular which is the idea of making money by transferring value between the various crypto-currencies as their value changes with respect to one-another. Usually Bitcoin is used as the base currency since all exchanges that offer multiple crypto-currencies allow them all to be bought or sold with Bitcoins.
