Not sure what your question is here, but to clear some facts, there's no 0 confirmation sells on those BTMs anymore, so on any amount you should wait for transaction confirmation, I suggest using higher fees than average. The other is Identity confirmation that depending on where you are (Country, state, ...) differs but usually if you want to do more than the daily limit of $100 (this amount may vary) you have to scan your ID to be verified.
