If You Bought From Silk Road, Coinalytics May Have You Mapped
http://cointelegraph.com/news/112988/if-you-bought-from-silk-road-coinalytics-may-have-you-mapped"... Other coins are getting more traction in online free markets, too, among them Darkcoin. Using a feature called Darksend, the Darkcoin protocol automatically mixes every transaction with the inputs of two other transactions. Its basically what youd have if Satoshi Nakamoto had written Bitcoin Fog right into his protocol.
Darkcoins price went from 75 cents to seven dollars in just a month earlier this year when a few online free markets began to accept it. So while those who dont mind being mapped by the likes of Coinalytics are good to go with Bitcoin, the desire for transaction and identity privacy will likely lead to further growth in other cryptocurrencies and tool-packed wallets."
