I usually kept $3000-$4000, then needed to pay major debts for awhile. So since then, I average 1000.
I don't keep much on my PayPal. I just keep exchanging to E-Gold or spending them and opening few sites and promoting them. I keep less than 200$ on my PayPal.
I always transfer it to my bank account when it gets to $100. Paypal pays more interest, but I trust my bank more.
seems im just poor. i spend far too much. i have $100 there right now. I once had $8000 thanks to CH and LT
