Most major economists on television and news outlets are saying Bitcoin is worthless. I'm going to use that "expert" analysis to do my accounting for trading Bitcoin. I don't see how they could tax your trades as the value of the coins fluctuate so rapidly. I think they are only talking about cashing out Bitcoin into fiat currency, but I'm no accounting expert. I will just play dumb as I don't plan on converting any of my holdings into cash this year.
By my opinion this "experts" thin that bitcoin is worthless because it is not very well regulated by legislation, and they do not really understand the nature of crypto currencies. I think that bit coin and any other alt coins constitute a future of the economics.
