Though its a fishy act of blenderwallet, but for the response of its users I guess, it's okay to assume that they're totally helping. Hampuz didn't comment regards on this as well knowing he still managing their campaign.
After reading abve comments, i can't deny my doubts that i am using my signature to promote an ambigious service. I am still not sure about the statut of blenderwallet with this accusation.. And as i trust manager Hhampuz, i can tell that i am also waiting for his attitude about the actual situation of Blenderwallet.
