1) Huge price premium when buying BTC locally with cash (how many Overseas workers get paid is cash) - not everybody has a Coinbase account connected to his bank
I am so sorry to hear that you have no proper bitcoin exchange established in the Philippines.
2) Buying Bitcoin with Coinbase and bank account has 4-7 day delay - everything about Bitcoin is slow
Poor 3rd party services are to blame, not bitcoin network. If you have no access to real bitcoin exchange it can be a problem.
3) Many workers have never heard about Bitcoin or are scared of it - they need a system that is very simple to use
I bet that here are much many workers who know what bitcoin is, than people aware of Pesobit existence.
How are you so different that any other altcoin, AFAIK you don't offer Pesobit to fiat exchange and you can't use Pesobit directly to purchase anything.
