Bitker is Singapore registered exchange. Good trading volume as well as decent liquidity makes it one of the top 30 exchanges (in my view). This exchange offers trading in a large number of cryptocurrencies and has offers multiple trading pairs.This platform was designed by in-house IT department, providing 24/7 online service in multiple language. Bitker doesn;t state that US-investors are prohibited from trading unlike many other crypto exchanges. So you can call is an investor friendly exchange though it doesn't support fiat deposits which is a bit discouraging for new investors.
Talking about fee, spot trading fee is around 0.1%. Users in contract trading can also get rewards for providing liquidity which is lucrative. Bitker users high-efficient trading engine to improve the user's trading experience. With wide range of trading pairs, good user interface makes it a quality exchange.
Talking about community ecology, it has its own exchange or lets say community token BKB. BKB holders can participate in community ecological autonomy and voting to self-govern BITKER community, and all data are open and transparent which is kinda cool. Talking the fee structure, the maker fee is 0.1 % and same fee is for takers as well. Withdrawal fee in bitcoin is 0.0005 which is not bad in my view.
To conclude, i would say that the BITKER virtual currency exchange provides hundreds of pairs, is secure and reliable for users from all around the world. But to maintain the fame it has to face tough competition from rival exchanges to emerge as a bigger exchange. See you soon, Revainers !!!
