My take -the Crypto 6 charges summarized: FTL was paid in BTC from an advertiser, so was able to accrue a good amount over time. Ian then picked up some BTC vending machines, and started exchanging some of this to willing buyers, in exchange for fiat federal reserve notes. He didn't pay the taxes that the feds thought he should be paying. No one was defrauded, no individual or company filed suit against him. Just a long and expensive investigation into what can be summarized as tax evasion?
