anybody know when old balances will be returned?? been so long now

Yes. Never.
They have no intention of allowing the so-called "solvent" coins to be withdrawn by their owners or they would have made them available months ago.
If this is the case why the hell did they take over crypto rush, it should have been left the way it was 'a fail and a scam', should have launched a complete new exchange with new name etc, in my eyes until all old funds are given back anything with the name Crypto rush stinks and i will stay well away.
I think exactly the same way. If they want people to "trust"and use their exchange, they should start giving back the solvent coins.
