nah, it's a casino. crash will come eventually, the complication is that both bulls and bears want the same thing in the end....higher those lines go up the more $ the people who know how much the underlying is actually worth can cash out.

a crash/correction is just someone cashing out and either not putting the $ back in or atleast actually putting thought behind how they put it back in. the real suckers are the ones buying into everything automatically no matter the price.
