You can earn ethereum through campaigns by participating on it, like participating to a social media and signature campaigns that are offering ethereum as a payment. You just have to follow all of their rules and accomplish your job properly to be able to be paid weekly.
There's no campaign that is paying in ETH.
Most of the campaigns are paying in bitcoin and for the bounties they are paying with their tokens which you can trade for ETH.
Of course there isn't, they are shitposting to increase post count for campaign.
I do not know what you're talking about, but I did not meet the bounty that would pay for the promotion in ETH or BTC - the bounty pays in its currency, which it promotes, but I do not exclude that such companies exist))
That is new, bitcoin forum and there isn't campaign which is paying in btc. Do you have bitcoin sections on ignore?
