At the very least his prediction in
this thread has come to fruition(see the last reply on the thread). That being said, I believe he is not utterly clueless, his prediction might become true again this time and being overly bearish it is just his way of saying things.
just because someone predicts some price and it comes true it doesn't mean they are good at "predicting bitcoin price" and it certainly doesn't mean their future so called predictions are going to also come true.
you can roll a dice 10 times and win in a dice gambling game but that doesn't make you a future teller.
