Does the new message on Cryptopia.co.nz and Twitter mean, that all my funds on Cryptopia are lost?
Not lost per se, but the company is entering liquidation proceedings. If you have a balance on Cryptopia, you will need to make a claim with the liquidators or trustee in the coming weeks or months. Then you'll wait in line with all of Cryptopia's other creditors who are hoping to get a fraction of their money back.
This could be a long, drawn-out process. It could end up taking years, like the Mt. Gox bankruptcy.
