Actually theres a bounty that's pay in BTC already you can see it in services in this forum some of campaigns that pays in BTC is signature. But now its few bounty that pays in BTC because as we all know that bitcoin is dropping that's why it's rare to find a bounty that pays in BTC.
You just missed the whole discussion.
It's a bounty that wants people to subscribe to his channel but it was deleted because it was a fake one or what I think is because its duplicated.
