Coinbase accidentally deposited $400 to my account, how long you think it’ll be before they correct it? Not gonna spend it unless it stays for like a month…

Posting here and not r/Coinbase just because I think I’ll get more interesting responses. Obviously this is just a glitch but I could definitely spend that money now because I have a Coinbase card. I don’t really want to cause trouble with Coinbase and get my card deactivated so I’m just gonna leave it on my account for now. It’s kind of confusing because it makes it harder to track how much spending money I actually have. Anyone else get a free $400 in their account? How long do you think it will take them to fix it?

Edit: I didn’t get any notifications about the deposit. The only way I see this working out in my favor is that a transaction on my Coinbase card may have accidentally been refunded by a vendor. It’s weird that the money went directly to my Coinbase card as USDC, not like a bank deposit would…I’m not spending it now, I expect it to be gone tomorrow…at the very least I am earning my 0.15% interest on it so this is a win either way????
