There are numerous ongoing bounty programs who are rewarding the bounty hunters by stakes model and sometimes bounty hunters are disappointed by the fact that ICO's don't meet the softcap thus the users do not get any benefit for their hard work or sometime they receive too little rewards for their hard work due to stakes systems, do we really need stakes system or the best thing will be provided a fixed amount of tokens for bounty (like $100 work of tokens per week or so)?
Having a fixed amount of tokens is not beneficial for the project you are supporting. They could end up in debt if they only reach the softcap and still paying the bountyhunters in full amount. Stake system is there to reward the competition and more better because it is more of a support for the project their working on. Yes, it is saddening that bountyhunters could not be rewarded if their project didn't reach even the softcap but that was the job was built for, to promote the project to gather it's desired funding.
