These posts such as the OP's bear no purpose other to reinforce how the OP bought at a higher price, is concerned about the price dropping so pretends to express glee at the lower price and make fun of sellers. The sole purpose of the post is to stop people selling at ever lower prices, and certainly not because the OP is happy the price is falling. If a falling price made cheap bitcoins even cheaper the OP would be sitting quietly buying up bargain bitcoins and would do nothing to stop people selling.

You know, that could be the case for the OP. Or then again, some people like to gloat about things.
But speaking of how a lot of people on these threads are, you're probably right. But if that person is smart or has additional money, he/she could take a short position on the downward trend instead of hoping for it to stop (assuming that he/she thinks that the trend will continue on for a while longer).
