A man became a millionaire overnight after recovering millions of dollars in Bitcoin (CRYPTO: BTC) that he had lost access to 12 years earlier.

The Quest for ‘Lost’ Bitcoin

U.K. resident Chris lost access to his cryptocurrency wallet, which held roughly £4,000 ($5417.67) worth of Bitcoin, when the trading platform Intersango collapsed in 2014, according to LBC News.

Chris’ journey with Bitcoin began in 2011 when a friend persuaded him to invest in the cryptocurrency. He cautiously bought roughly $2031 worth of Bitcoin through Intersango, one of the earliest Bitcoin exchanges in the U.K.

However, the platform began experiencing serious problems in late 2012. By early 2014, the website had gone offline, and users who tried to withdraw their funds received no response. Chris also found his account frozen.
