> A lot of other countries dont have that luxury

The intersection of (a) countries with reliable Internet access and broadly-available Internet-connected devices, (b) a useless national currency and (c) effective controls on the use of cash hard currency is small. The GDP of that intersection certainly doesn't support anything close to Bitcoin's price.

You don't need A. Re B, which countries have a useful currency really? Say Hungarian Forint. Do you consider that a useful currency?

Ok what do you think would be a justified price and why?

A useful currency is a stable currency with predictable small inflation or deflaction. It doesn't really matter if this currency is implemented with people having "faith" in the currency, backing the currency with real assets or via a blockchain without a central bank.

A "currency" that can rise or fall by 30% on a single day is not useful as a currency.

We are very early on. Like' it's still very much in the beta stage.

I can't think of a national currency that is useful beyond faith.

Using a blockchain as a ledger device is far, far different from investing in a cryptocurrency.

> the project run by the United Nation's World Food Programme (WFP) was designed to direct resources to thousands of Syrian refugees by giving them cryptocurrency-based vouchers that could be redeemed in participating markets.

They're not really using the actual Etherium blockchain in any meaningful sense though. They just gave vouchers that could be spent at participating markets. It reeks of a marketing ploy by Parity Technologies for some press.
