Big project, good initiative, if they can not raise money to list in an exchange, make a mining pool Monero, ask the miners hcn to mine Monero and with the first mining block pay an exchange to list humanitary coin.
I think if we can't raise btc for listing, we can make pool and everyone can help us with it. First time people on pool will mine Monero, till we can be listed. After it, ALL our fund (200k HCN) will be shared for miners. Maybe, it is good idea.
Good luck with reviving this coin. To be honest, 0.12 btc listing fee for an unknown and small exchange with 700k volume is way too much.
You could try to list your coin on coinsmarkets imo.
