-----END BITCOIN SIGNED MESSAGE-----
So I did this back when coinbase allowed us peons to sign messages.... but we can no longer do this now.... so I have no way to sign the message ever again.... and no way to do anything in the future to recover my account. So Ill put this out here now since a few weeks ago i swapped my password to something with a lot more entropy... and at this point i can't think of a way to be able to securely recover my account; unless I can send funds to that address, and coinbase doesn't push them around between wallets on me before I can spend them on a verification TX to someone like phillipma1957 whom I trust and have done plenty of business with... I need to TX some funds to that address and see what happens. *note* on blockchain.info, that BTC address is labelled with my username.
Any input on the matter would help. I'm sure others are in the same boat as I am.
It's too bad you didn't stake another address before you changed your password, but eh, water under the bridge now.
How about this scenario: Stake an address with some funds in it, send the funds to your coinbase address, then send back to your new staked address. Even if coinbase shuffles your output address if it's all done within a few minutes and it's the same amount minus fees, that's fairly solid evidence it's still you.
