Wouldnât you agree that the required amount of liquidity Nu needs to provide depends on the amount of non-parket NBT? Because I think this is were our basic disagreement is.
In mean you basically say that a parked NBT is not different to a non-parked NBT. But if I consider buying NBT today, I would like to be sure that I can sell this NBT tomorrow. If Nu can proof the reserve for the unparked NBT and the parking graph shows me that no additional NBT will enter the market until tomorrow, then I will be confident that I can sell it, and might also be willing to pay the fee for it.
Again, I think the focus group should be two kinds of customers: short-term users (hedging, money transfer with stable value, etc), who have to pay the bill and long-term users (parking, retirement money etc) who basically lend money to Nu and therefore might even get something back. By balancing parking and burning rates you can define any other user group in between as well (e.g. availability once a month).
Yes, from exchange to paper wallet wonât work anymore, thatâs right. Of course, someone could provide a little online service that receives the exchange transaction, parks it and sets the paper wallet as parking address. Wouldnât be trustless of course, but easy to develop.
EDIT: actually, after a bit of thinking, this service could solve the offline wallet issue entirely as long as it can be trusted well enough. maybe FLOT should set something like this up. Otherwise I am pretty sure @backpacker can write this up in a day and if you then charge 0.1% fee then you could make a pretty good deal considering the development effort.
