"However, due to recent related emergencies, the platform is undergoing investigations by relevant public security departments. BKSBEX has decided to suspend the withdrawal function from 14:00 on May 10, 2021 and other functions will not be affected".
The above quoted text is the summary of what I came across on the Telegram of Barkis Blockchain Exchange also known as BKSBEX. Barkis Blockchain Exchange is an Estonian based exchange which was fully launched in 2019. Currently, the exchange doesn't offer any trading activity nor is the webpage accessible hence the exchange has no trading volume and haa even been tagged as Untracked Listing on CoinMarketCap. You won't want to trade here for now since withdrawal isn't possible.
