Bcoin.SG was a centralized exchange that trades digital assets in a very customized trading environment. This exchange came into the crypto market in the year 2018. I have think here and there, to know why exchange at the first time in service will be extra good, and a year after or two years after it establishment will begin to misbehave. This is exactly the case of bcoin.SG . presently on telegram I checked and I discovered that the exchange has not been active for over months and has a message from telegram team that if in the next 8 days the exchange does not come online they will be no sign that the exchange uses telegram again.
