I’ve never heard of BCD until I saw that anomaly of huge price difference between exchanges that begs me for some arbitrage action – except that the BCD wallets are closed on most of the exchanges. That sounds like a consiracy to me.
Conspiracy isn't it?
I'm also surprised that it was now at #37 on coinmarketcap.
You may buy bitcoin Diamond at a web such as: Binance, YoBit, gate.io,...
Better use binance instead of the said two though I don't have experience with gate.io but we all know that binance is one of the best exchange today.
I hope that they'll not be the same as others that the more customers they got, the service are getting more weird and bad.
There's many exchange that has BCD to trade.
This is their website
