I can't wait till everyone sells at like $600 or $800 and it keeps on rising as they watch in horror.
That's why one should never sell all his coins at once. If you just sell a small percentage of your coins at a time, then you can benefit from the price that goes up and up. If you sell all your coins, then yes, you'll hate yourself when the price goes up much higher.

Well, if everyone starts selling and goes over the support line then a price correction might very well happen and price is surely to drop. I don't specifically hate myself after selling a percentage my coins when the price goes up much higher because, as a person, as long as there's profit, all is well. But it would've been nice if the profit was higher though.
