Bitcoin Versus Government : Is Bitcoin the new gun rights battle ? — RT Op-Edge

Will Bitcoin, a stateless, decentralized, anonymous crypto-currency that has leaped in value from less than $1 mn to over $1 bn in just a few dozen months, succeed where the pro-gun rights advocates have failed - in protecting Americans, and people around the world - from an encroaching class of warmongering kleptocrats?

Bubble or No, This Virtual Currency Is a Lot of Coin in Any Realm

His conclusion, as of July 2012, was that $1.2 million in business was carried out each month, much of it for buying small amounts of narcotics that were delivered by mail. “We did see it was growing,” he said of the total value of the trades. “It pretty much doubled in the six months I followed it.”

Excluding the traders, he said, “#Silk_Road probably represents a sizable amount of bitcoin exchanges, but not more than half.”

Tiens, aujourd’hui, ça a crashé.

Bitcoin hits new high before losing $160 in value in one day

Bitcoin, the digital currency, lost more than $160 (£104) in value on Wednesday, just hours after hitting a record high.

The currency hit a new high of $266 before falling to $105 and then bouncing back to $130. The fall is unlikely to put off speculators. Two months ago, a Bitcoin was worth $20.

With Europe racked by economic uncertainty following the banking crisis in Cyprus, there have been fears that a “bubble” is being created with speculators piling into the four-year-old digital currency. But Bitcoin has crashed before only to bounce back. It hit a low of $7 in August 2011 after hitting a high of $32 two months earlier.

Jon Matonis of the Bitcoin Foundation, the currency’s promoter, denied a euro-bubble was being created in an interview with Der Spiegel this week.

Wednesday’s wild ride came as someone gave away thousands of dollars worth of Bitcoins on Reddit, the social news site. News blog Business Insider calculated a Reddit user under the name “Bitcoinbillionaire” had given away $13,627.69896 worth of Bitcoins to Reddit users over the day.
