I have been seeing that bounty managers abandon to wear bounty that they are promoting or any other bounty but wear signature, I'm wondering on that, and why

They publish bounty in bounty section and come to service section to apply and wear signature. Is that not funny to you?
They do that because they understand that many bounty they promote will never get to the market, many will exit when you invest your money.
They apply in signature because they know bitcoin payment is king, in every exchange, every P2P transaction and easily converted to fiat.
Why do they manage what they are not sure of return and go over to keep applying in bitcoin paying campaign while you keep relying on them to deliver, help you to get payment. You know this may not happen because they have taken payment from the bounty team and also earn from signature campaign.
They come to apply to signature and can't do research on the bounty, that is why scam is more in bounty.
Why don't they bargain for payment with altcoins with high value like etheruem , bnb, USDT etc.
If I were the team, I will include it in the terms...
And the signature section too can help to stop this if they stop them to concentration making bounty better
And if this is done, you see shit bounties won't come up lol
I wonder that bounty managers still have to apply to signature campaign and get accepted and start the job of promoting another project apart from the bounty they are handling. This is funny indeed, hahaha

I don't think is encouraging to see. That is basically the concern
The irony of it is that they manage bounty but promote bitcoin paying signature. Lol
