How are you going to get scammed by any of these methods?

Moneygram/WU: the individual picks up the cash prior to giving me coin.

Cash deposit: Cash is deposited into a business bank account. I write on the receipt "no refunds, this cash deposit was done to purchase bitcoin" ...I then tear up the receipt.

Do you use your brain? Or are you just jealous that you are a poor sap?  Put your money where your mouth is punk.

Serious sellers only.
