Im shocked people are endorsing these 3rd party payment systems WHEN WE HAVE BITCOIN. Just buy some BTC and send it, fast, no fee.
It is not as simple as that. In the UK, it's hard to get bitcoins without trading privately though localbitcoins.org. The prices are typically very high. Demand outstrips supply significantly.
Seriously. And for any exchange site, you have to wait days to week, if not MONTHS to get your coins. Oh, and good luck finding a legitimate way to import USD so you can even buy your coins to begin with. And let's not forget exchanges (*ahem* Coinbase) cancelling people's purchases if the price fluctuates within a few days.
