I asked this question on reddit, but no answer so I will also try here:
I would like to ask about the economic value of BCA. I am not exactly sure but assuming that the new DEX works and gains acceptance what role does BCA play in this. Will people exchanging tokens need it to pay the fee for exchange? I am just wondering what would be the factors driving up the price of this coin. Apart from pure speculative value what role does BCA play in the context of Tritium? Is it possible that people avoid it completely using this DEX with for instance changing ETH to BTC directly?
If someone can discuss on this that would be great.

Our reply from Reddit:
Hey, thanks for your question

Please note that this is not our official subreddit, only the u/BitcoinAtom is. Holding BCA is incentivized by trading fees discount schedule for BCA holders. Scale is going to be progressive - depending on the amount of BCA held, trading fees might even equal 0.
