Many thanks for the answer. I didn't know that BKEX was a bad exchange. I have always bought and stored my coins in Binance. Since a few coins were not yet listed on Binance and only on BKEX, that's why I invested money there. It's been months and the stock market hasn't given any information or written a tweet on Twitter. I think all the money is gone and that really hurts...
Unfortunately, no authority intervened and wanted to examine the case and send these fraudsters behind bars...
