【A certain Bitcoin investor sentenced to hand over cryptocurrency private keys worth $124 million】On January 8, news broke that Frank Richard Ahlgren III, the first Bitcoin investor in the U.S. convicted of tax crimes related to cryptocurrency transactions, has been sentenced to two years in prison and ordered to hand over the keys to access his cryptocurrency assets. Court documents show that Ahlgren was accused of concealing at least 1,287 Bitcoins valued at over $124 million through mixing services. He previously pleaded guilty to underreporting capital gains tax on $3.7 million in Bitcoin trades and was ordered to pay the U.S. government $1 million in tax loss restitution. U.S. District Judge Robert Pitman of the Federal Court in Austin, Texas, ordered Ahlgren to surrender the keys and devices storing these crypto assets and disclose all cryptocurrency accounts. He is prohibited from transferring, selling, or depleting any property without court approval, but may use it for normal living expenses. Ahlgren's attorney, Dennis Kainen, stated that his client would comply with the court's directive.
