I wouldn't say manipulate but those speculators are trying to short bitcoin day by day that's why we didn't see a jump on the price. But seeing the price spike in the last 2 days? I wouldn't say that they can easily manipulate it as they used to be because a lot has been jumping on the bandwagon and doesn't want to miss the boat again.
As for those newbies being trap, I'm sure they have learned their experience in a hard way and and at a cost as well.
Yeah we're not getting any sudden drastic dumps anymore aside from the usual corrections. It's possible that majority of the weak hands have been flushed out of the market already and those that were left are those who understood the movements better. But manipulation of course can't be discounted at any time. Even if we don't admit it, the market can and would probably be manipulated by some people with the means to do it.
