Can i do this with multibit wallet?
If i will post here any exchange btc address ,Is it possible to signed message exchange btc address with my multibit wallet.
can i signed message for multiple accounts?
if you actually looked through the post that QS linked you, which I assume was shorena's guide to signing messages, youd see that the post included the step-by-stop instructions for signing and verifying a message on multibit. It is only possible to sign a message from an address that you control; ie, you can send funds from. if your address is on an exchange, then you must get the private key for that address imported before signing from that address (which is what i think youre asking, cant understand the broken english)
