Hello everyone!



I've got some questions on the head regarding PayPal. Can anybody please help me to understand those facts?



1. How does PayPal work when receiving money?



2. How does PayPal work for merchants?



3. Can I send money to my friend's PayPal account with Venmo?



4. What happens if you don't pay your PayPal negative balance?


5. How do you set up PayPal payments on an AliDropship website?


6. What are the fees for PayPal donations?



Thank you.
