Sooner or later you will get a limitation - and only a few of the people resolve the limitation and keep using Paypal.
The others are just screwed over. I would suggest you go with Business, as this may give you a longer life span before you get a limitation. Dealing with huge money constantly using a Personal account will trigger the filter / red flag quite quickly.
Trust me - I know a lot of things about Paypal. I have had over $XXXX held in funds waiting to be released so trust me on the fact that you will get limited, sooner or later, and when that does come you have a high chance of getting screwed.
