bitcointalk have everything we need if we want to learn about bitcoin info or other alt coin too, we just needed to look around and find anything we wanted to know its really helpful and informative.
i agree with this but bitcointalk like any other forum on the internet is giving people some kind of anonymity which makes them say whatever they want like for example if you check out the speculations boards then you can see lots of biased posts which they are lying through their teeth to get whet they want.
so what i want to say is that you should always try to learn how to find the good posts instead of any kind of FUD post and only pay attention to those.
There will be many people who will speculate the price of bitcoin and altcoins but no one knows what will happen in future, its good to spend time here but take decisions only after doing proper research on your own.
