"In more extreme situations, taxpayers could be subject to criminal prosecution for failing to properly report the income tax consequences of virtual currency transactions. Criminal charges could include tax evasion and filing a false tax return. Anyone convicted of tax evasion is subject to a prison term of up to five years and a fine of up to $250,000. Anyone convicted of filing a false return is subject to a prison term of up to three years and a fine of up to $250,000." https://www.irs.gov/newsroom/irs-reminds-taxpayers-to-report-virtual-currency-transactions https://www.irs.gov/newsroom/irs-reminds-taxpayers-to-report...

I don't know who is doing their taxes or legal prep, maybe they've got this all covered, who knows. UPDATE: They reply in another comment that they've been advised to avoid US sales for the time being. Makes sense.
