I tried barterdex but couldn't understand how to use it, nor I saw any sign of XBC there. I am ready to pay 50% of the listing fees for crex24. I've tried this exchange personally and its good. Don't look at the volume because they're atleast not faking their volume similar to fatbtc. THe total listing fees is 0.25 btc. I can handle upto 0.12 btc. Let me know if anyone is ready to pay the other half to get xbc listed on crex24.
I'll take you up on that offer and will pursue Crex24 to get a quote, in this depressed market you can often strike a better deal. I've spoken to Graviex and am getting us listed there, we could do with some back up exchanges after our run of bad luck.
We've finished the BTCPay integration but have had to leave it disabled due to Cryptopia going down, a fair amount of time has been lost, I'm hoping they will come back up but after reading the external analysis from Elementus it seems unlikely.
It would be awesome if we get listed on graviex and crex24. I can surely help you out with crex24. Once it's done, we can find few more people to contribute for the listing on Mercatox (1.4 btc) or Stex (1.1 btc).
