Join the queue Im afraid. I requested a withdrawl of just over 1BTC on Feb 25th, no confirmation email arrived, same for 1m Leaf. No response from the devs by PM, no response on here and nonsense updates on twitter.
It looks like this exchange has been hacked too, but instead of coming clean and doing something about it (like in the link above), coinmarket.io is doing nothing, posting no updates and has all but disappeared.
Sorry, but it looks like your coins, just like mine, are now lost forever.
There has already been at least one person admit to stealing coins from this exchange on this thread, so there will be lots more out there for sure. This exchange does not have the coins available for everyone to withdraw. Thats why they are keeping quiet. They have no answer to this problem and simply dare not admit it. If somebody finds out who they are and where they live, then I wouldn't want to be in their shoes. They could at least take the target off their back by admitting what has happened, but they are that dumb and disrespectful to people who used their exchange in good faith that they don't even do that.
