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.
You know what, It is still rather good to join in bounties here in bitcointalk forum mate. Because it is already proven and tested, aside from that bounty campaign in the forum helped a lot of bounty hunters here too to give an opportunity to earn altcoins and bitcoin too.
