I've heard and read many analysts actually optimistic about this last big dive in the market flow, they believe it's a signal for a big bull in the next semester. But I find hard to believe as I'm not seeing why exactly they see that, what you guys think?

Good. Don't believe anything that random idiots tell you in the name of analysis. Do your own research man. Just be positive,in general, know what I mean? Don't give a fuck what other people tell, but have faith in yourself and keep believing in good things.
I do not know whether this bearish market is good or not, but what I know is, the price won't be down forever.
