because everybody want to get rich, and tought they missed out the bitcoin -buy in
That is how it seems to me as well. Although BTC are still increasing in value fairly rapidly. Just a few days ago when I set up my first wallet the value of a bitcoin was about $90 USD. Now it's over $110 USD. I doubt this rate is sustainable (and I hope it doesn't continue on actually for stability reasons) but it indicates there is still money to be made by speculators.
