So we've all seen this in the past few months. AB puts extra BTC into your account. What do you do? Scrap the account? Or just leave it there and use the account? Let say <200$ extra. Use all of it and then scrap the account. Whats your thoughts? Obviously if I was the guy with 8 BTC that showed up in my account I would be gone but what about less amount.
As long as you've always used good opsec, withdraw and tumble the coin. The second they know about it they'll take it back, they have no reason not to.
