Since the IRS has declared btc to be property, be sure to hold large amounts 1yr +1 day so you can get capital gains treatment.
What happens if you sell it before a year is up? What is the tax % then?
And what is it compared to if you hold it for over a year?
-edit- nevermind. I found a good answer to my question here:
http://www.investopedia.com/terms/c/capitalgainstreatment.aspDefinition of 'Capital Gains Treatment'
The specific taxes assessed on investment capital gains as determined by the U.S. Tax Code. When a stock is sold for a profit, the portion of the proceeds over and above the purchase value (or cost basis) is known as capital gains. Capital gains tax is broken down into two categories: short-term capital gains and long-term capital gains. Stocks held longer than one year are considered long term for the treatment of any capital gains, and are taxed a maximum of 15% depending on the investor's tax bracket. Stocks held less than one year are subject to short-term capital gains at a maximum rate of 35% depending again on the investor's tax bracket.
