The assumption of the article is a paradox. The author first assumes that the total bitcoin market will be worth 1 trillion. Then he claims people will hoard coins due to their promising future value. In reality, there is a chance the bitcoin market will reach 1 trillion. There is also a chance it will crash. Most likely it will fluctuate. If I were told there was a 100% chance my 1.5 coins I have mined today would be worth hundreds of thousands of dollars, then of course I would hoard. But since I have no such guarantee, I am more likely to cash out when I think the market has peaked and/or the fad has faded. There are die hards who will hoard and have hoarded from day one. It's the same with all investments. I have a friend who bought his new car with 11 ounces of gold - He walked in, set it down on the table, sign some paperwork and walked away with a new car. But I think the average bitcoin user won't be able to pass up the idea of "I didn't really have to do anything for this, so why not buy a pizza with a few (micro)bitcoins."
