We need to embrace the reality now, if you earn 1000$ worth of token from any bounty just be expecting 50$ to 60$ when it get listed on exchange, it's hard to see a new project that will maintain its ICO price after listed on exchange, market needs to recover to start enjoying bounties once again
But that is not very realistic anyway, you are making many assumptions, to begin with which bounty campaign is going to pay a single participant 1000 dollars on their own coins? Most campaigns offer rewards that are way lower than that so you are going to be lucky to get 5 dollars after months of work, another assumption you are making is that you think you are going to get paid when many bounties are not paying their bounty participants using all kind of excuses.
