Problem right now is that a very small group of people, less than 5000, hold the majority (90%+) of all the coins minted so far. People in this group want to sell them for $$, but there isn't enough new capital to meet their supply at the moment. It will take a long time and tons of trading to spread out the coins from a small 5000 group of miners to your 272.000 people.
The question then is why would 272.000 people hold 25 BTC each ? Bitcoin is not an invesment. People's greed and speculation ran up the price from April $1 to June $30+. It could happen again, and again or it could not. Bitcoin will still preform same functionality either its price is $0.5, $5 or $500 per coin. People greed for fiat money wants it to be more.
As long as mining is still as profitable as it is right now, prices will keep sliding lower overall. Bitcoin *real* US$ value is between $1 and $5 right now depending on electricity cost and work put in to mine them. It will take a major change in bitcoin usage for price to start rocketing again anytime soon. We need services services and more services for that to happen.
you absolutely have no clue about the electricity bills of the average miner if you think $5/BTC can cover mining costs.
I guess that guy was slow to the show!
