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.
Bitcoins are 'worthless' based on the economic models they studied on the university, blockchain monetization is a real concept. In regards of taxing definitely is a difficult task and will add a complete new layer to currency trading... Also, how would taxing affect miners?
