Others had talk about the forum for cryptocurrency discussions
Who does 'Others' refer to? Do you mean people in general? I don't really understand what is your confusion in this since this forum is all (or mostly) about cryptocurrencies and their discussions. Have you really surfed the forum yet? Thoroughly? I assume you didn't, otherwise THIS question would've automatically been answered if you did that.
and earning profit by any form of.bounty hunting
That is an optional/additional thing and isn't something the forum was fundamentally created for. As soon as the forum became too populated, it started to attract advertisers, and those bounties/campaigns are the results of that.
and even sometimes scamming other users.
That is a shameful act, but not a way of earning. Bad things exist, not only in this forum, but everywhere you go.
But does forum has mission, vision or and core values?
The mission/vision is to provide information to everyone about Bitcoin or cryptocurrencies in general, and the purpose is served very well, if someone have the ability to absorb it. Otherwise, if someone is not interested in learning, he would find it to be useless.
Do we have an approach to grow users here in the forum and spreading positivities about cryprocurrency? Just asking..
What kind of an approach do you expect? Do you want theymos to record motivational speeches and broadcast them in the forum in order to spread positivity and grow the users?
We don't need anything else. The ones who really reaches the forum for the purpose of learning about cryptocurrencies in general would not require any approach, but would adapt the things and would stay around to get even more, and the ones who find the forum to be only a source of income would never really care about anything else that exists in here. So we are all good, I guess.
