Based on what I read Matthecat is a day trader who makes several short term predictions on a daily basis. Of course when you make that many predictions you will come up wrong at a higher rate, but overall his predictions have been good.

Others who make long term predictions about the market look more accurate because they make few predictions and the price can hit a wider range for that person to look correct.

At the same time, its not a pissing contest. Obiwon if you think it will hit that price in 2 days better throw alot of fiat on the exhanges and buy, can make a very quick return on it apparently. And now since you have judged others analysis expect the same to happen to you (if you dont disappear on March 4).
