If BTSX fees are inadequate to pay the delegates' expenses, but BitUSD fees would be, doesn't that create an excellent incentive for delegates to do a hard fork which changes the fee distribution at that time?
Or are we worried that there may be non-updateable clients in the wild at that time, and hard forks will cause those users too much pain?
Getting rid of subsidies is more disruptive the longer they've been paid. We're better off fixing the problem earlier.
Conceptually, I think the ideal is that transaction fees should pay for the real costs of transactions, and shorts should pay longs a variable amount depending on the current demand to short. Is there any disagreement on this?
Yes.
Today she shorts seem in great abundance.
We will have to change the system to make their life more bearable, long before we reach Visa-like transaction volumes...
I'm not understanding this. Are you saying we need to make it easier to short?
The primary argument here is that in a BitUSD only use case (consumer->merchant, BitUSD<->USD), they pay nothing to the network (only other BitUSD users). This could yield VISA level transaction volume with no compensation to the delegates.
The delegates would have to make their money from margin calls and order submission/update on BTSX orders. Here is the fact of the matter: market orders will always out number consumer->merchant orders by an order of magnitude. So assuming there are 4 market order transactions for every consumer transaction then the speculators can easily cover the costs of the consumers.
Speculators are in the business of making money from their transactions so the fees don't hurt them nearly as much.
Where do you get that market orders will always outnumber consumer orders by an order of magnitude? More relevantly, are you implying that this will remain true not only globally, but in our specific market, regardless of the incentive structure we impose on that market? O.o
Are you saying the speculators should subsidize the consumers just because they can afford it? Since they're focused on making money, rather than on convenience in spending, I'd expect fees to be a stronger deterrent to speculators, especially when they can find lower fees in other markets in which they aren't subsidizing others.
