Ver refused to comment on the matter to Decrypt or acknowledge the lawsuit.
Ver is facing jail time after the feds last year charged him with avoiding paying $50 million in taxes, along with alleged mail fraud and filing false tax returns. He has since embarked on a campaign to get the charges dropped.
The cryptocurrency entrepreneur was one of the earliest investors in top digital asset firms like Kraken, Ripple, and others, and gained the moniker "Bitcoin Jesus" because he was an early investor and reportedly used to give away digital coins for free.
But he then became known in the crypto space for promoting controversial BTC spinoff Bitcoin Cash, claiming it was the "real Bitcoin."
Ver, who served prison time in 2002 for selling explosives on eBay, renounced his U.S. citizenship in 2014 and became a citizen of St. Kitts and Nevis.
Spanish feds last year arrested Ver in Spain after U.S. authorities ordered his arrest, alleging that he sold Bitcoin in 2017 but had not informed the IRS about the gains he had made.
Ver previously told Decrypt that he was hopeful the campaign would help catch the attention of President Trump, who pardoned Bitcoin icon and Silk Road founder Ross Ulbricht in January. Trump also later pardoned the founders of crypto exchange BitMEX, including outspoken crypto bull Arthur Hayes.
President Trump has been friendly towards the crypto space after receiving financial backing—and votes—from people in the industry. A number of SEC lawsuits and investigations against crypto firms have been scrapped since the Republican came to power.
