Well I wouldn't say that it's too much aggressive, it is usual campaign, and it is only signature campaign and they pay on their own currency so they are not spending any bitcoin or any fiat money but the reserved money.
And yeah the rate is good enough and the requirements are not too high, I have seen campaigns that require up to 30-40 posts per week which I would say in that case this is aggressive promoting, at the other side there are campaigns which require only 10 posts or less per week depending on the campaign.
They also are running the twitter campaigns which is very effective and yahoo makes his job just perfect!
Yeah, the lowest requirement I have ever joined is 20 posts per week and that was not even close to paying $30 per week. I do not think we should see it as good or bad, signature campaign is a tested way of promoting a project. I would have gladly joined if I did not already have a campaign, as GBYTE is one of the very few alts I followed from my earliest days (and I bought most of my byteballs.
That rate will be very good when gbyte reaches its ATH again, so trust me, that is one of the best methods to earn right now. I only hope the participants do not dump, and actually use the wallet. They will be so surprised to see how special it is!
