"The IRS issued guidance on the treatment of Bitcoin and other digital currencies in their March 2014-21 Notice. The notice clarified the position that the IRS treats digital currencies as capital assets and are therefore subject to capital gains taxes. Any disposition of these digital currencies, including trading and spending, is a tax event and capital gains must be calculated in USD."


I think it is important that you support, use and endorse Bitcoin even if you don't manage to make significant changes. Although I'm not a US resident (nor citizen), I sincerely hope you succeed.
