IDCM is a Chinese exchange that is based in Hong Kong and Target Asian market. iDCM is an acronym for international digital currency market. It support more than 55 currency pairs. It was launched in 2018 by a team made up of some crypto enthusiast.
The exchange has its own stablecoin which is pegged at 1:1 ratio with Hongkong dollar. Apart from it's own stablecoin, other available cryptos are tethe(USDT), Bitcoin and many more.
There transaction fee is charged on a flat basis from makers and takers. It charges 0.20% which somehow higher than what is charged by other exchanges. Withdrawal fee is 0.0005 BTC which is within what is obtainable in the market.
Personally I don't see anything that makes the exchange to really stand above others.
There are lots of negative reports concerning their customers services and delayed in withdrawal confirmation.
