I posted this in the Crex24 Discord group:
Everyone I wanted to share an update from my end as a Dev from BTCT (Bitcoin Token) listed on Crex24. I have spoken with their staff and they are working through a security issue as a "pre-caution" against any potential problems. This is what I really like about Crex24 is that they are very cautious towards security and that is one reason for their long confirmation times with depositing etc.
My suggestion to everyone is sit back and wait at most this will be just 3-4 more days and everything will be back for normal. Trading is still active.
