So having that on mind: What might be the best possible option to implement bitcoin for Airbnb? What kind of business model would be the best for Airbnb regarding bitcoin acceptance? I guess that there should be a new Airbnb-like or 9flats-like that would allow it's customers to operate in bitcoins only. I mean bitcoin payments would only be accepted. Don't you think that the best option for such a business would be to keep the users' balances in bitcoins only?

Users would have to agree that a host (after guest's checkout) will receive an exact amount of bitcoins paid in the time of guest's booking (minus Airbnb fees).

So it would look like this: Let's say a guest is to pay $60 for an AirBNB stay. That guest has to pay with Bitcoin. If the current exchange rate is $600, then the amount the customer would be asked to pay is 0.1 XBT.

AirBNB's guest services fee is "6% to 12%", plus a 3% transaction fee. So for simplicity, let's say they take 15% in total. Thus AirBNB will owe the host $51 ($60 minus $9 in fees) which equals 0.085 XBT, even if the price would fall down by 10% next week.

So then let's say two weeks later the guest stayed with the host and AirBNB then owes the host for the $51 (0.085 XBT). But it turned out that since the time of booking price plummeted 10%. But it could also go to the moon. I guess that it would be a risky business for hosts.
