@meme_hunter might help you to ask for update to the team since he is the one managing the contest which means he has contact to the team that responsible for contest here in the forum.
Do you win in all of them and none of the 3 contest paid you until now after 3 weeks of waiting?
Since they have a running campaign and are managed by a reputed campaign manager, you should not be worried about the payment. Since the campaign manager also asked you guys to wait a little more, you should allow them some time. I believe there is a communication gap from the Betbolt official side, which is why they either didn't see the manager's message, or they did not respond to it.
Sometimes the person in contact could be unavailable, or the person who can credit the rewards may not be available. Whatever the case is, allow them some time and see what happens. BTW, Betbolt is recruiting people for their company, check their X account. I think this is a good sign.
Is that true?
Yes, What he said is true.
