When it comes to missing coins – they're usually down the back of the sofa. When it comes to missing Bitcoins – apparently they're usually in a stray digital wallet that you'd forgotten about, or at least that's the case with MtGox.
At the end of last month, as you're probably aware, MtGox filed for bankruptcy following the theft of a massive amount of virtual currency (850,000 Bitcoins, including some 100,000 that belonged to MtGox itself, the rest to customers).
The latest development, as the BBC reports, is that MtGox has discovered an old digital wallet from three years back which contains 200,000 Bitcoins, worth around £70 million.
MtGox CEO Mark Karpeles commented: "MtGox had certain old-format wallets which were used in the past and which, MtGox thought, no longer held any Bitcoins."
"On 7 March, 2014, MtGox confirmed that an old-format wallet which was used prior to June 2011 held a balance of approximately 200,000 Bitcoins."
The virtual currency was shuttled away to offline wallets late last week, to keep the cryptocurrency safe from any other potential Bitcoin pilferers out there, Karpeles noted.
However, this development has caused a few raised eyebrows, unsurprisingly given the anger of customers who were out of virtual pocket when MtGox was suddenly shuttered last month.
Previously, hackers posted a huge amount of data (including reams of transaction details) taken from MtGox's website to Karpeles' blog, and accused the CEO of hoarding the Bitcoins which he claims were pinched. This old wallet discovery probably isn't going to sit well with these folks...
