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.
There are many private bounties here, but still for me bitcointalk forum remain good for bounty hunters and investors. I already tried it before on bounty guru but now its not existing anymore, but not sure about it, then bountyhive and etc. But my experienced there wasn't good actually because up to now they never pay me.
