This is another middleman service for payments, similar to that Flexa one.
Well, its about time apps like these appear, but a decentralized p2p marketplace would be better in my opinion.
Good that more services are adopting bitcoin, but I agree with you, I think there should be more p2p services adopting btc as payment method and not only the middlemen ones.
Unfortunatelly it's not going to happen because most businesses won't want to take the risk of holding btcs, they prefer an intermediary to take the risks of volatility for them.
