The Jewex exchange can still be rated as a new exchange taking from ts starting point history which dates backs to 2019. The exchange though still appears to be operational from it's website which shows price orders that are actually tracked to the current prices in other markets. In checking with the order books of each of their pairs in the exchange order book, I could see that there was a huge gap between the selling and buying orders meaning there is a wide spread that will leave the efficiencies in the market. With this in mind, this exchange cannot be an option to trade with or use
There are also other issues bordering the exchange like being regarded as an untracked listing on CoinMarketCap, no sign of volumes, inactive social media handles and an unresponsive support team. I wouldn't recommend sending funds to the exchange
