An anonymous reader writes “A Chinese Bitcoin exchange has vanished without trace, taking more than $4 million of the virtual currency with it and leaving profit-hungry investors out of pocket. GBL, the Chinese Bitcoin exchange was launched in May 2013 and putatively based in Hong Kong, despite its servers being registered in Beijing. However GBL’s Hong Kong offices do not exist. GBL mysteriously disappeared in early November taking an estimated $4.1m (£2.6m) of Bitcoins with it.” (Beware the auto-playing ads, with sound.) Read more of this story at Slashdot.
