If Bitcoin is going to take off, you've got to use it. I just talked to a customer service guy at Newegg. He said 'hardly anyone' pays with bitcoin. He said he's only dealt with two orders done in Bitcoin.
If you've got bitcoin, go spend some buying cool shit at Newegg or Overstock. The whole thing will fall apart if Merchants start seeing it as a waste of time.
Don't wait, buy some shit today! What are you - an idiot?
