Well, there are no forums which can be compared with Bitcointalk. There aren't many active users on alternative forums, not much discussion. But at least there are less spam
.
I think you also can add forum.bitcoin.com. Yes, it's website of Bitcoin Cash, but despite that it's not bad forum. And also - Bitco.in/forum , Bitcoinforum.com
I checked few your links. Jackobian.com and digitalmoneytalk.com aren't Bitcoin/crypto forums. It's just forums about money making online which have boards dedicated to Bitcoin and cryptocurrencies. Well, then there are hundreds of similar forums which have crypto related boards, I'm not sure it's worth to list such forums there.
However, there are no bounty for these sites. There is a special website that can do bounty. I think that although there are many bounty on BTT, most of them are not high quality. You cannot get appreciable benefits.
Can you tell me, why you are using forums? To discuss, learn something or just to earn money. Ok, it's rhetorical question, you don't need to answer it...
