BtcShark Exchange is a digital assets trading platform. It was launched and registered in Singapore in 2019. Being from Singapore, I had already expected this exchange to be the ideal trading platform for traders since all the exchanges I used from Singapore were all satisfactory. But it turned out to be the contrary to what I had expected. After checking the out the exchange on CoinMarketCap, i discovered that it had been featured as an Untracked Listing and the link to the exchange provided, shiwed that the exchange wasn't accessible. Even using the link provided by Revain gave me the same result. While surfing the internet, you might come across phishing website with similar name to BtcShark, it's advisable not to try and access such URLs as they might be a scam replica of the original BtcShark
In conclusion, traders should stay away from this exchange since its current status isn't known.
