I certainly do want to see this initiative to succeed. However the previous trials to establish Bitcoin cities have failed.
Arnheim City has seen a decrease in the number of Bitcoin transactions after an initial hype, despite all the efforts of BitKassa. Who has heard about Gent Bitcoinstad? Amsterdam as a Bitcoin City? Barcelona and Madrid Bitcoin Streets?
These things did not work because there was no positive feedback and no incentives for the people there to use Bitcoin. Only efforts by Bitcoin buffs who have no idea about how normal people live and work.
If Phillippinos use phones and scan Qr-codes normally to pay then Bitcoin is not at a disadvantage from start. In my country I prefer cash to Qr-code scanning every day of the week.
The second necessary step will be to get enough incentives that workers spontaneously want to get paid in Bitcoin, but I expect this to be very difficult.
Anyhow, good luck, and maybe the huge remittance market in the Phillippines will push normal people over the edge.
