basically the electrion commity can buy bitcoins for investments. bt for tax reasons cannot spend bitcoins buying products or giving away, thy must cash out to fiat before doing anything with them..
Nothing to do with tax. Election law. Looks like they couldn't come to an agreement on its status as commodity enough to approve usage for disbursement.
in short. buy to hoard investment. not buy to use as currency
Neither draft A (Republican) nor draft B (Democrat) would have allowed bought Bitcoins to be used other than as investment; A (and our compromise proposal) would've allowed it for Bitcoin received as a contribution and kept unliquidated.
Also note that C doesn't say it's illegal, it just doesn't opine either way. In theory we could sue them to get a final answer; not sure whether we want to our have the financial support for it.
Either way, it's still a significant positive step towards "legit" use of Bitcoins as a means of exchange, which'll probably improve over time.
