To be honest, I like BitcoinTalk, because it attracts many members, there are many interesting & rewarding discussions. Bounty hunters also easily find more opportunities in bounty campaigns.
However, for some unknown reason, my account was blocked on BitcoinTalk even though I did nothing to violate the rules of the forum, it was really confusing.
Currently I'm quite satisfied with AltcoinTalks, here we have better admin & Mods, we have Telegram channel to discuss, we have very effective local communities. I find the Vietnamese community here, which is the best thing I have never had with BitcoinTalk.
