Guys, I am new here, and considering investing a nice chunk of my portfolio (10-20%) in bitcoin. I have several questions:

#1 How does the government treat BTC gains tax wise?  Are there rules in effect?  Are capital gains the same as a stock sale?
#2 Whats the best method to go about buying bitcoin in the US?  Coinbase, or is there a cheaper marketmaker?
#3 Has anyone tried doing technical analysis on BTC prices, and if so has it worked?
