Is the 'Bitcoin address used from GLBSE' a withdrawal address used while GLBSE was active, or the recovery address provided to GLBSE after it went down?
I do not know. Only 1 address is on the GLBSE list. Maybe OgNasty knows. But it does not matter. After your account is activated you set the address you want to use.
It the second one: the recovery address provided to GLBSE after it went down.
That's the address Nefario send to all issuers.
How should he know the other address?
