I think that the timing is not entirely the major point here. We pay out everyone by wire transfer so that they get the money on or around the 15th of each month. However, this incurs costs both for us and for you, the amount depending on your specific bank. PayPal is the cheapest, fastest way to pay you out and we normally pay PayPal a few days early. It's certainly our favoured method of payout due to the ease involved.
