A couple of times, i have got private translation bounty requests that not listed on bitcointalk. i think there are several bounties like this, not official listed on bounty thread but profitable for hunters.
For example, telegram managers for a good project, they earn stably by managing telegram. however, we cant find those bounties in ordinary participation only. Exactly private bounties.
I think that there are not a few examples like this.
and I want to hear about private bounty experiences you joined.
To be honest,I believe that even now we can earn efficiently through this industry.
In 2017 ending i join a private bounty through my Twitter account after receiving and email from the developer to help in promoting his projects on Twitter. I was handsomely rewarded with good tokens that I convert to bitcoin early last year. I have see and know that such bounties exist and it is not only on this forum that we can participate in a bounty. We are having other bounty sites like bountyalert, bountyhave and bountyox that developers do meet bounty hunters.
