ALEX could have been a millionaire. It was just applying our PC hardware to a global network, something novel. In the early days of GPU mining, a single card could mine quite a few coins per day. As it progressed, the bitcoin program grew to gigabytes in size. It kept on ballooning so eventually I deleted it backed up the small encrypted wallet file to keep on my USB stick. US980, he suddenly remembered his wallet. USB stick back in to try and access the file, but the stick died.

Never back up anything on a cheap Chinese-made disk or USB stick. Unfortunately, Alex’s story is not unique. As bitcoin mania reaches fever pitch, attention is turning to bitcoin’s missing billions.

When bitcoins are produced, they have a private key associated with them.

It works using key-pair cryptography — you have a public address and a private key that go together. The public address is what you use to send bitcoins, the private key is what you need to spend them. If you lose the private key, because of the mathematics involved and the strength of the cryptographic system, which is what makes it so safe, it’s impossible to ever get it back. What’s commonly happened is people have just deleted the file off their computer — the text document that holds the private key. 100 note or losing a gold bar off the side of a pirate ship, Mr Davidson agreed that the ease with which bitcoins can be accidentally lost forever at the press of a button — particularly given how valuable they now are — can make people uneasy.
