Choosing between 2 different models doesn't imply no profitability for
the DAC. It's just a matter of setting up those 2 models. Flat vs
Percentage for example. One thing doesn't imply the other imo. It's just
a matter of reaching consensus here. With two options should be easier
because that way we can have one that benefits people who think fees are
too high and others who think fees are too low.
Sure. My reasoning was that no matter what model you chose, the end user
will always need to pay a fee. And unless you can opt-out from the
referral program on a per-asset basis, 80% of that fee will go to the
referral program (except for ltm)
Well, assuming it's the businesses that choose the fee model which their
users will use, what if they just keep changing the fees? What about the
first users who used a more expensive fee model before and the new users
that get the new benefits of the new model? People will no be happy,
even though the market will decide to continue supporting that business
or not..
Sounds like business as usual to me

Will old users have a different model than new users? Will the fee model
change for all users if the business who registered them chooses to? I
assumed it won't. Can parameters from thousands of accounts be changed
like that? While others aren't? There are lots of stuff to consider
there. Maybe I'm going too deep already but I assumed they wouldn't be
able to change because of that. Of course if it can be changed, I see no
problem. If users find it unfair they will just move on to other
business. That was my first assumption, maybe a wrong one but the
initial one I had, hence my comment above.
Oh, wait, I think we are talking different things here. I am not talking
about makeing a distinction among USERS, but among ASSETS.
So, for instance, a user of asset TUSD does not need to pay referral
bonus because TUSD has opted out of the referral program. That, however,
does not mean that the referral fee is discarded for any other asset as
well.
