This is one of the few markets where I'd consider share-dropping a valid strategy.
I hate blanket non targeted share-dropping on Bitcoin or other alt-coins.
I'm also not even a big fan of big deposit bonuses on debit cards to Mainstream.
However I would be in favour of giving a deposit bonus or even a $10 free sign up bonus to BitPagos customers as I know most of them are using Bitcoin as a volatility & part store of value hedge, exactly what BitUSD does much better and that many will REALLY want it, once they're exposed to it imo. (A high conversion rate I think it's called.) Also I don't know what the right bonus is, but the per capita income there is lower so you can bring in new users and build network effect in that country with a much lower incentive (cost) needed per user .
It could also be an angle to get BitPagos on board. I would also politely but clearly explain to them that their Bitcoin based business model is obsolete in that country. Their customers are specifically looking for what BitUSD offers, so they will lose market share if they're slow on the uptake.
One market can also spread it worldwide via remittances, they'll start asking for BitUSD from family working overseas across the world. Those overseas workers will then expose their overseas colleagues and friends to BitUSD, who will then send it home to their families in countries across the world. Anyway yeah I'm in favour of really focusing on a few key markets like this as a way to spread BitUSD I think.
