I can't imagine why Coinbase wants to wait a full 30 days before extending you credit, considering that on your first transaction you basically bounced a check on them. LOL
Coinbase isn't your babysitter. You made the mistake, now wait out your time in the corner like a good boy. Sheesh.
I had actually made sevaral deposits of 1-4 btc before this, a total of maybe 780 bucks... so screw you assumptions make an ass out of urself you know...
Depositing BTC in your own account is of no concern to Coinbase or proof of your honesty. You tried to buy BTC with an empty account. Now you have to take a "time out" and sit in the corner for a while.
