A long time ago many people said that they should never keep assets in the stock market, it would be risky if something happened like Upbit and IDAX, but keep it in a safer cold wallet.
IDAX exchange has been controversial for a long time but never used it after much news about IDAX with many fake volumes and other embezzlement.
Actually I have also heard that IDAX Global has cheated on some IEO projects, but I do not feel anything strange that they do to traders like me, so I keep trading there, until something bad happened a week ago that they lost the CEO those who run away with our assets are traders. fortunately I have transferred most of my assets to my personal wallet
