Bitcoin's fourth largest exchange, VirWox, just posted a record for weekly volume traded of nearly 30 million Linden Dollars (SLL), or $115,000 USD. The previous record was set during the Bitcoin bubble of June 2011.
And in case you think this might be caused by inflation of the Second Life currency, the exchange rate has actually remained extremely stable, holding between 250 and 270 SLL/USD for the last three years. Notably, this exchange rate is managed through "printing" of the currency to keep up with demand.
The largest exchange, Mt.Gox, has seen its market share drop, with weekly volume continuing to dwindle and flirt with yearly lows. The loss of Bitcoinica, which conducted all of its trades through Mt.Gox, will no doubt add to Mt.Gox's woes in the coming weeks and months.
