I struggle with all, sadly
Bio Food Bucket - Only "bio food" or "bio bucket" would be appropriate
Bio Technology Bank - Biotech and banking are completely separate sectors, I don't see the "banking" side of biotech ...essentially technology products related to biological systems. I just don't it, in my little opinion
Virtual Digger - Don't like the pairing. I could get behind "dig digital", that's pretty sweet
Hope you get offers on them
