Participating in such programs that pay with bitcoins or other top altcoins would be the best solution for bounty hunters when paying for their work in the boun. But there are not many such programs on the forum. In addition, there are restrictions on the number of participants and ranks. This is why it is very difficult to join a signature campaign with payment in bitcoins.
I agree, it is one of the best choices. This new pattern encourages us to improve the quality of our posts and activities in supporting the project. Usually, campaigns that pay with BTC or top altcoin have special criteria and are more difficult than general campaigns, for example in a join signature campaign, they must get a number of Merits, a quality and constructive post history.
