I don't know if this is the Coinbase address he meant
Yep, that's the address he said it was from Coinbase as its the only one that he mtnioned in that "Stake your Bitcoin Address" thread.
No one to quote.
Here is mine, the one I have used through this forum:

With that beind said, he used some other addresses that he could use if he wants.
