If they use Bitcoin the international orders will be less complex.
Why? You can't pay a freight forwarder, a cargo company or duties and vat with bitcoin so you still cannot complete an international order only with bitcoin and you need the help of the banks.
Also explain me what security gives to an importer right now paying with:
1 - an irrevocable payment method like bitcoin.
2 - In case you use a multi-sig transaction to make the transaction revocable, (trying to do something similar like a letter of credit), you will need to wait 30 to 50 days for an international order by sea to arrive. With the current volatility nobody will accept to receive a payment in bitcoin.
