Who knows, but the Match Billion site looks good, and I think they will keep promise with rewards.
If they do keep promise, the token in bounty pool and partial tokens for signature campaign will not change, and less participants, higher rewards at the end for each participant.
it's the basic thing with stake-count bounties.
I can say this is very generous campaign and in telegram admin said there won't be kyc, but I do have one question, will token reward pool remain the same for signature campaign if less participants join?
