It is MYR sorry,but I withdraw them to MRY address and it seems success .I am very confused .
Are you saying that you were able to send MYR from Poloniex to an MRY wallet? That can't be right. Please give details, wallet address', transaction ID's etc.
I can confirm this is possible because i sent over 60k MYR into a MRY address and it worked, Lyckuily the sysop from xnigma was able to help me retrieve the MYR by installing the MYR address and putting the wallet.dat file into the roaming and letting it sync.
I am sure this works vice versa. Now you would just need to download a MYR wallet and do the same and it should have the balance in your MYR wallet!
