Not entirely. They usually keep an eye out for trades 500m+, and 2b+ is already a red flag in their radars most of the times. If you haven't done like many trades on your IP and don't RWT that often maybe you'll be a bit safer. But it's always better to be safe than sorry, so take any extra precautions if possible so you're on the clear; eg don't trade the entire 2b all at once.
