Hi all,

I've been loosely throwing an idea around in my head / on paper and was hoping to get some constructive feedback / advice on where to go with this.

The problem I'm trying to solve for is being able to give travelers easy access to local fiat currency while abroad through matching buyers with sellers / holders of leftover cash from their past trip. All while being able to do it in real time at a physical ATM location in a country the traveler is currently in. So for example, Traveler A wants to visit spain, and while there needs access to $500 USD worth of Euros. Rather than getting housed on fees at the local TraveleX outside the train station, they can go up to one of these ATMs, log in, and be matched in real-time with a group of past travelers (travelers B, C, and D) who have funds leftover in their account which accumulates to the amount Traveler A needs on the spot.

Basically Traveler A or anyone else for that matter doesn't need to worry about high commissions, excessive fees, international transaction fees from their home bank, having to go to their home bank ahead of time, or worry about not having a credit card that works well overseas.

Essentially there would be one blockchain that is used for the Traveler A buying from Traveler B, C, and D. There would be no actual trading allowed on the exchange since the matching of buyers and sellers would be fully automated. At least that's my thought, and this is what's holding me up:

I need to figure out 2 things. 1) how would this type of private and non-tradeable exchange work? Basically I want to make sure that on the exchange between Travelers A, B, C, etc. there's no day trading of the token that this will be based on. the way I envision it, the value of fiat held on by former travelers is just expressed as fiat values, but stored in some form of a token or coin. It's not tradeable except for on that exchange, but it's pegged to some real world currency to remain stable with token supply. 2) creating a token for external exchange trading that's a financial incentive to mine / verify transactions happening on the private exchange. I don't know what existing blockchain to base it on. I like the smart contracts of ETH, or how quick transactions happen in BCH, but I also like the POMA of HTMLCoin and its insanely fast transaction times.

Lastly, the physical ATMs are a different problem, but almost a little bit easier to solve for, but that's a question for further down the line. Right now as I figure out my first two problems, I'm simply assuming the ATM works magically and just does what it needs to do.

I hope this makes sense and i'm not just blowing smoke.

Thanks
