In only a month, the little-known bitcoin alternative known as Darkcoin has rocketed nearly tenfold in value–from around 75 cents a coin to almost seven dollars. Its selling point: Darkcoin offers far greater anonymity than bitcoin, mixing up users’ transactions so that it’s incredibly difficult to trace a payment to a person. And though few have yet to accept that more-anonymous coin for actual goods and services, the promise of Darkcoin’s privacy features seems to have sparked a miniature boom. It’s one of the fastest growing among the wave of cryptocurrencies that’s followed bitcoin’s success, with the total value of its combined coins topping out at nearly $30 million.

Darkcoin’s uncanny growth, of course, may also be fueled by speculators who see an opportunity to jump on a hot commodity. And given how wildly it’s appreciated in its short life, there’s no guarantee it won’t crash just as fast.

Same here. If the Enigma code could be cracked, this Crypto-things will also be cracked. I know some geek will quote 128 bit encryption or even 1024 bit. Forex makes more sense than such.

I'm very skeptical about Bitcoin and other cryptocurrencies. Has anyone in this forum actually used Bitcoin in a transaction?
