I'm not sure what the bounty was like in 2018, but it's definitely not paying like it used to, though there are a few managers who bring in good projects and are rewarded significantly.
However, getting a good project in bounty currently is a matter of luck.
so join into best manager which is have good selection for each campaign they will managed. I am believe if you to him , atleast chance to scammed by dev team will decrease alot. alot bounty campaign have good potency in future as long as we didnt give up and keep working.
I think soon or later bounty system will be vanished.
i dont think so , if more already multiple year we are here and everyday we see new campaign launched. if we find scam campaign its normal because alot project occur but it doesnt mean everything will done.
