Any signature campaigns that actually pay in prominent altcoins like Litecoin, Eth, Dash or similar top alts that are high on market cap?
If bitcoin, its a yes ( for the reason of it's popularity ) . But other token as payment , uhm not possible folks. Mostly, if you join in newly create alternative coins ( altcoins ) , it pays their own coins. For the mainly reason that, their own token has a value too that you may use someday. Also you already a part of their project, so you must benefit those coins or token than any token like you mention. If they pay you other token than their own, it's clear that their own token is already defeated in this competition here crypto currency. Hope I explain it well to you.
