If your local politician starts soliciting donations in Bitcoins, don't be surprised: the US Federal Election Commission just approved the cryptocurrency for political contributions. Now, politicians and political action committees (PACs) can accept Bitcoin, so long as donors list their names, addresses, occupations and confirm that they own the coins they're sending over. Recipients can't spend those contributions as Bitcoin, though: they first have to convert the money into US dollars and then deposit everything with the rest of their campaign funds. If the cryptocurrency donations aren't instantly converted through a payment service, the recipients will have to declare their value based on the day's exchange rates... and we all know how quickly those rates can fluctuate.
