high likely that they are connected one way or another. their partnership means one, few or all of them are also owners of this new DEX. this may be favourable to BFG token holders as they can take advantage of some features like low exchange fee, high yield in farming etc.
Of course, if the owners are the same, this is convenient from the point of view of the convenience of regulating the circulation of the token itself and convenient for users, since the interfaces and fees are approximately similar.
Maybe just ask devs how the exchange is connected to their site?
And how interesting they scared everyone with a minimum output of 5BTC... which then turned into 5000 sat.
This is probably their humor.
I appreciated this humor!
