I can give you more than 20 crypto forums right away, I mean, both you can learn for free and not gain anything and those you can earn and learn from. But the catch is, there is no other forum like Bitcointalk, that's the truth, this forum is designed selflessly, with a unique plan. So you can only see imitations that are money-centred themselves, and it's obvious in their modus operandi.

https://www.altcoinstalks.com is a good example of that imitation.
