They won't, because this is a garage project, and they use 3rd party services, so their fees never will be competitive. There are plenty similar ones, and they come and go. It can be an exeption, but hardly will be.
If Hive spend money for it, they should do a proper one, a competitive one, but that cost lot more - starkers made a vid with this manu guy few months ago about their tests, even that looks more promising.
In the end, it's all about the money, if you can't offer competitive prices, you will go down.
HBD-HIVE-USDT can be converted for very small cost, and then the above mentioned fees are near the best ones, so if you wanna operate with 2-4x fees, you gonna fail, obviously.
Nobody will pay that 2-4x just because this service is more direct.
Anyway, the core Hive team (i know, noting like this exist) don't use the Hive futures listing given benefits... still don't use it. Even Binance can be reached by this or other market leaders.
I mostly use the above mentioned crypto DCs, and they have really crappy coins listed, for example that bit2me has around 400 coins what can be swapped on their site, topup asap and spend + they have direct crypto payments option for travels (all have something similar, where you really can spend crypto) with discounts.
They even have 'Listing request' form on their homepage... just have to fill, and if Hive meets with legal requirements, they will add. Just have to go after a bit, but if they wait, how crim wrote, that others come to them and say, they want to come to Hive, then just similar ones will appear.
