Following the recent developments about airdrops which is not guaranteed to earn from it at the ending after taking parts in their various media activities, they will end up building their social media pages with participants at the ends paying trash and peanuts. now talking of bounties, most at time it pays but that is dependent of the project team to put effort collectively to make the project succeed before you could sell or converts your bounty tokens to stable coin or BNB. in most scenario some project owners don't pay hunters after promoting for their campaign.
I don't know why you say that rewards are not distributed until the project succeeds. After all, all the conditions are described at the very beginning, including the date of payment of the prizes. If you don't like when you get paid for participating in the campaign, you just don't take part in it. If the project does not want to pay bounty rewards then you have to create a scam accussation.
Yeah its been mentioned on the beginning but doesnt mean that it would be an assurance that you would get paid on the said date because most of projects do really delay it up or doesnt really have the plans to pay
up their advertisers or bounty workers and this is one of things which do suck when you do deal with bounty hunting on where you cant be sure if you would get paid or getting paid but the token do end up on having
no value thats why its up on someone discretion whether they do deal up with the risk or simply avoid it.
