I asked the people who run Crypto-bridge on their Discord channel, they said the devs had paid for the listing, but they don't give the exact when they will list BSX on their exchange, they don't give this information to the public, but hey at least we know the devs paid for the listing. POW will end at block 450010, so whether you believe in BSX or being impatient, so watch out for it. Remember Bitcoin in the early day.
There are many others exchanges: stocks.exchange, cryptopia, coinexchange etc. Crypro-bridge is not one. Why they don`t listing on different? I think these investments would be more reasonable for everyone.
Why don't you give them some btc, so they can list on other exchanges? Be a human and have some patience, mate.
I totally agree with you!
