Sorry for the long silence, it takes time to sort out things like this.  As per our usual response, if we detect something wrong with a blockchain where the dev _might_ be involved, I like to post a public statement so everyone has the same information at the same time.  Exchanges were informed earlier today when our security measures kicked off.

There seems to be a problem with the "lucky" staking code from what we can tell at this time.  There are blocks that were accepted with POS rewards up to 3.3M which is why outside the rate for the coin.  Additionally, as of right now there are way more coins in existence than the wallet thinks there should be:

    "balance" : 24751980.90800208,
    "stake" : 0.00000000,
    "blocks" : 4655,
    "timeoffset" : 0,
    "moneysupply" : 21073266.40374496,


This is our current supply.  C-Cex and yobit have another combined 5-6M.  At this time, we don't know if this is malicious or an error in the staking code.  We have cancelled all orders on the market and closed the wallet for the time being.  If the devs can please contact us and come up with a solution, we will reopen the market.  If we an agreed solution cannot be agreed upon, we will close the market and open the wallet for withdrawal only.

thanks,
