So my friend has made his first purchase from AB. He bought a 1/4 lb. of cannabis. Before purchasing he sent his coins from a reliable Bitcoins vendor and then sent them to his electrum wallet (still CN) after that he sent it accidentally to his AB account before tumbling. So in a hurry he pulls them back out as soon as possible and puts them into a tumbler. After the tumbler he sent them to a new AB account. Should my friend be fine with the coin situation and should a 1/4 lb. be okay as well? He's getting kind of getting scared because it should be at his house tomorow. Any help and tips would be helpful.
He'll be fine. The only problem he'll have is the "bitcoin vendor" closing account if it were coinbase. Other than that, it does not matter, all they know is that the coin went to a DNM market.
FYI: AB has a built in tumbler so when you pulled it out, it was tumbled, and you retumbled it.
