<p>More than 4,000 bitcoins – an amount worth approximately $37 million as of press time – will be auctioned off by U.S. law enforcement officials on February 18.</p> <p>The U.S. Marshals Service <a href="https://www.usmarshals.gov/assets/2020/febbitcoinauction/" target="_blank" rel="noopener noreferrer">said on Monday</a> that it will put up 4,040.54069820 BTC on the auction block on February 18. A $200,000 deposit is required for those wishing to participant, and would-be bidders must register by February 12. </p> <p>The Marshals Service held its first bitcoin auction in the summer of 2014 – which, as reported at the time, saw investor Tim Draper <a href="https://en.bitcoin.it/wiki/USMS_June_2014_auction" target="_blank" rel="noopener noreferrer">win</a> nearly 30,000 BTC across 10 auction blocks. A number of other auctions, including more coins seized during the U.S. government's investigation into the now-defunct dark marketplace Silk Road, have been held in the years since. The most recent took place in late 2018. </p> <p>This month's auction will see four blocks – 2,500 BTC, 1,000 BTC, 500 BTC and 40.54069820 BTC, respectively – during the event. </p> <p>"The USMS will notify all bidders about their eligibility to participate in the auction by email no later than 5:00 PM EST on Thursday, February 13, 2020," the USMS said in its statement. </p>
