So bitcoin came to mind as what might be the ideal solution to such a problem because a person anywhere in the world could send coins directly to the recipient without having to trust any middlemen. And since even the most destitute of countries seem to have mobile phone service, a "feature phone" bitcoin client could provide the means to receive and use the coins.
Until Bitcoin gains traction as money where it is recognized and accepted widely enough to function as a currency the recipient might instead still be better off with a money transfer or hawala even with exorbitant fees.
That's why Bitcoin adoption needs to start catching on before the crisis.
The way for that to happen is for there to emerge money changers who will act as the money transfer agent. This is how M-PESA grew -- agents become M-PESA agents because they were earning commissions, sometimes better than they were earning from their other work.
These agents simply can work independently.
So here's the scenario I envision.
1.) An individual receives a text notifying that bitcoins were added to the mobile phone's (hosted) E-wallet.
2.) Individual coordinates with the Bitcoin agent to arrange a meeting time and place (.e.g, cybercafe, hotel lobby or other public place -- for safety) of both.
3.) Individual sends a text to spend bitcoins to the Bitcoin agent's address (e.g., "send 1.23 btc to 50922345678" ) 50922345678 being the Bitcoin agen'ts phone#
4.) Bitcoin agent hands over the cash
Coinapult can do this ... it works in the U.S. and Canada now. They were waiting on their text messaging backend (Twilio) to expand their global footprint I believe.
The problems with that are if this type of exchanged is not welcomed (and we know it likely is not) then SMS transactions are not secure (sent in clear text across mobile network.) So at a minimum, the transfer from the individual to the Bitcoin agent should be not be traceable. So I figure the send message basically just gives a PIN code that the individual then shows to the Bitcoin agent who then has a method to retrieve via SMS, using that PIN.
The next problem is where the individual Bitcoin agents then also need to convert the bitcoins that were received in order to restock the cash supply (and to unload the exchange rate risk exposure. So either other Bitcoin agents nearby might trade with each other for a small fee and eventually a larger agent ends up with a number of coins and then either trades them with local investors or transacts such that the cash stock gets replenished in a timely manner.
So that's one idea as to how Bitcoin will emerge in these areas. Basically anywhere there are tourists as well as tourists arriving might want to buy local currency with bitcoins and then sell their levftover fiat before leaving and get bitcoins for the trip back home. These areas are hotels, B&Bs, cybercafe's, dining establishments even.
