Sistemkoin doing scam with our funds through unable withdrawal. Yesterday i sent request to withdraw my tokens from sistemkoin, showing pending verification for a long time.
Your funds are as good as gone. I have been in this forum for 3 years and I have seen about 3-4 scam accusations about them. Next time you plan on using an unpopular exchange like Sistemkoin I suggested you do some due diligence. For example a simple search of "Sistemkoin Scam" will give you search results of different scam warnings, reviews and accusations.
Even their trust pilot page is full of people complaining about the scam exchange
