I believe in bitcoin and space travel
BUT! I don't believe that we need these bitcoin fiat processors. They will replace the banks, but they do exactly the same.
With Bitpay we have even more middleman than in the fiat system.
Bank -> Exchange -> Bitcoin -> Bitpay -> Exchange -> Bank (Bitpay) -> Bank (Merchant)
Well, if both users use coinbase..
Bank -> Coinbase (user) -> Coinbase (merchant) -> Bank
if user already holds bitcoin
Bitcoin -> Coinbase -> Bank
