Yes we can, because of the relative opportunity costs of holding Bitcoins and dollars. You may as well say we can't live in a world in which the market expects stocks to steadily increase in value compared to the dollar. Dollars are far more liquid than Bitcoins (or stocks) and, in equilibrium, you have to pay for that liquidity.
If the market expected the price of Bitcoins to steady increase people would buy Bitcoins today increasing Bitcoin's price, until the price of Bitcoins was high enough so that people wouldn't be confident that it would keep increasing.
