Questions
1. Can someone explain how mixing takes place within MS, is it between independent owners of coin or can coins be mixed directly with issuers supply?
2. Will Controllable negate the ability for a user to effectively mix a coins?
3. Also need some clarification on Exchange Booth fees, does the buyer pay both tx fees for buying and selling a coin?
Here is a scenario (assuming mixing can take place with issuers supply)
Issue a coin as both Exchangeable and Controllable. This way the coin can't be traded on open market.
List coin on Exchange Booth offering to sell 1 coin for 100 Nxt, and offer to buy 1 coin for 100 Nxt.
Buyer buys 1 coin for 100Nxt, spending an additional 1 Nxt for Tx fee.
Buyer mixes coin (I'm assuming transferring ownership to another Nxt account)
Buyer then sells 1 coin back to me for 100 Nxt on Exchange Booth, spending 1 Nxt for Tx fee.
Buyer spends maximum 102 Nxt to mix 100 Nxt.
I'm still unclear on how exactly mixing takes place. If it has to happen between users, then I would make the coin only Exchangeable and issue an extremely large supply so there is no secondary market and then of course put up a very large buy order on Exchange booth so the buyer never pays more than he/she paid and tx fees to mix coin.
