Hmm, Gambling is never encouraged, from my concerns and perspective it should be heavily discouraged but as here we are an open forum you can discuss anything in specific sections for Bitcoin here is a full section related to a sub-section of Bitcoin, and for gambling, there are also some child sections.

In order to learn about trading we can discuss here and on some level even educate ourselves but for learning, I cant see any proper material, back in few months I tried to start a full guide on this forum for the basics of trading where I did cover some basic stuff in total 4 topics but they are also incomplete at least need 4 topics to cover basics only and as it takes too much time to compile data and with response of audience in my views its futile.

As most of the people there discuss emotional training for trading, in my own view as well video tutorials are way more helpful to absorb the massive information, here in different topics there are some limitations like the most frequent one is language.
