"In the absence of a market to establish the price (of bitcoin, estimates) based on production cost is a good guess and a helpful service (thanks). The price of any commodity tends to gravitate toward the production cost. If the price is below cost, then production slows down. If the price is above cost, profit can be made by generating and selling more."
the current levels are still undervalue for the actual production cost of bitcoin, so definitely it's a better time to buy at these levels.
Did he really wrote this? There is no way to 'generate more coins' - the algorithm adjusts the difficulty so that on average it is always the same amount produced in a given time span.
