i always withdraw the second i get payment, and it paid off. some asshole buyer decides to open a case against me faulting me for not shipping the item (despite having a tracking number, despite having tracking information, despite it not being delivered yet). paypal put a hold on my account which gave me a negative balance. after a week of being ignored i escalated to ebay customer support which resolved the case 'in his favor' but let go of the hold on my money, so my balance is back to 0.
stupid ass paypal and ebay. been a member of ebay since 90s and paypal since their first year or so and still have to deal with nonsense from some pos 15 feedback having asshole.
