Bittrex staff has informed me they have successfully upgraded to EverGreenCoin version 1.5.0.1.
C-Cex as well.
EDIT: C-Cex is still in maintenance. They must be performing a reconciliation still.
Bittrex is confirmed. Happy trading!
Great, is it just yobit to go now? Their wallet is reported to be offline - block height there is 892449 - dont have access to my wallet so can't see if they are on the new chain or still on the old one...
Only Bittrex has been confirmed at this time. So, cryptopia, c-cex, and yobit have not been confirmed.
By 'confirmed' I mean their wallet has been upgraded, brought out of any maintenance mode, and verified by sending and receiving. Do not send or try to receive from an exchange until you see an announcement that the exchange has been confirmed to be on the proper blockchain and is operational.
Sorry if any of my posts were misleading. Just because they have 'upgraded' does not mean they have removed any maintenence mode, resynced if they need to, performed any internal reconciliation, and been tested.
