Decentralized Currency Exchange based on Reputation

This is some something that is far from being thought through but I started writing a draft of my reasoning/thinking and as I am now stuck in my thinking I will leave it here. Maybe someone can find my unfinished and rudimentary thinking inspiring and/or worthy of more thinking.

Decentralized Currency Exchange based on Reputation

In this exchange system you have two addresses of two different cryprocurrencies associated with a percentage of reputation.
You can only swap from one currency to the other one sending the amount you have in one of the currencies to all those that have reputation and are swapping to the currency you currently have. One of the addresses needs to become with zero balance after each swap. You can only swap to others that have reputation so if you want to withdraw to an address that has no reputation associated you loose all your reputation marks. The system calculates the amount you have to send to the participants you are swapping with based on their percentage of reputation.
The more reputation they have, the more percentage of the amount to swap you will send to them.
Everyone will make a bid for the price at that swap. The price is then calculated as the average of each price bid multiplied by the reputation percentage of the corresponding bidder.
Everyone has to agree to send all their swap amount at that calculated price or will loose all their reputation.
The less time you take to fulfil the swap the more reputation you will get. Also the more swaps you have done so far the higher your reputation will be and the harder it will be to drop you out.
