Is there a way for you to restrict access(limited access) to these accounts?

I'm interested in hearing what others have to say as I have been wondering this myself about giving away sensitive account access. However, I would have to side with hoodoof. You're in a position right now that's a sure thing and it's bringing you money. You never know what lies beyond so I would milk it as well. Yes, you can find even another source of income just as lucrative, if not more so, but you can also wind up not finding anything and losing your current income. Be careful not to underestimate how difficult it is to get to where you are with your current business just because you're able to do it once. It's well known that luck plays a huge roll, and with that said, I wish you the best of luck.
