Armstrong wrote of the rumblings of gov’ts plan to asset tax us, add up your assets and cash and take a %. Thing is, you have to sell something to come up with the dough. Argentina first one out of the gate.  On a side note, how do I sell my home in bitcoin when it fluctuates so much, I would rather use a currency that is constant. Sure there is currency to currency differentials but is is relative to location but to assume world wide use of bitcoin for is going to work I cannot fathom. Buy a new F350 today and the next day bitcoin drops 30 % will not fly. Will it max out in coin count and then stay at a constant price and how does it expand with population growth and avoid the huge fluctuations???  Will 10 bitcoins buy the same truck in Canada as in Peru ?
