coins need 50 confirmations to trade (speaking with exchange about this to reduce to below 10)
I have spoken withe the owner at Flame Exchange and he promised to return all qrk2 that was on the exchange, just pm him on his Discord channel.
He did send me all my coins.
He also said he would return the BTC in the near future. The total amount taken was under 1,000 euros.
I am working on getting listed now. Will know where in a few days.
It was 2-3x profitability of mining RVN when you could sell it.
