“On Feb. 4, 2014, Ver allegedly obtained citizenship in St. Kitts and Nevis and shortly thereafter renounced his U.S. citizenship in a process known as expatriation. As a result of his expatriation, Ver allegedly was required under U.S. law to file tax returns that reported capital gains from the constructive sale of his world-wide assets, including the bitcoins, and to report the fair market value of his assets. He was also allegedly required to pay a tax – referred to as an “exit tax” – on those capital gains.”
