Imo its all just luck i've done two 1b trades where i sold 1b all at once two different times and i never got banned, but my friend once sold 500m and he got perm banned so i'd just do it safe and do smaller trades or trade it to a mule and then do it from that account.
Normally don't really play but last few days my friend asked me to help him bait people so been doing that with him for fun made 37m yesterday so wasn't too bad.
