is it possible to focus on speculating only, reading nothing else but all the speculating topics and then somehow becoming better at speculating than others?
no, i don't think you can gain any actual "expertise" by
only reading all speculations. not to mention that you would be wasting your time since more than half (if not 90%) of the bitcoin price related speculation you see on the internet is pure nonsense written by newbies who either have no idea how the bitcoin market works or they have some agenda behind what they publish like wanting to fill their shorts or spreading FUD in general!
in my opinion the only way to gain any real experience when it comes to speculation is if you start analyzing the market yourself. and only spend a little time reading what other people say.
