It really depends on your buytime..as long as it wasn't too low, I think you might be fine! I ABed a 20mil stamp once, waited like 3 days, transferred it to my main and then sold it.Worked for me, both my accounts are still safe! If you're wondering, my buytime was around 1.6-2.2, I don't really remember..
Good news My buytime was around the same as that. It was actually the first item I've gotten that day
