hello, there anyone tell me
1.if the bays need transfer to client or the qt wallet will always be there so it is ok in wallet?
2. if need transfer then how? it seems i cant use the wallet.dat in client and find the bays directly.
You do not have to transfer your Bay to the client. For now both wallets work. That said, we do recommend that you use the client for a number of reasons.
Your wallet.dat from the QT wallet can not be used in the client because the client is multisig. You have to send the coins from QT to client.
