You are allowed 10 listing or $500 total.
The $500 total means that if you list 1 domain for $500 then that's your limit used.
Like I said in my above post, been selling domains there since 2008 (some over $2k) and I've never had to wait for any cash. It's all been instant to my PayPal.
The reason people have to wait these days is because they are new and on some kind of probation period. eBay had to bring in a product guarantee system, if you don't get your product, then you get your money back. To save eBay from paying this, they hold the seller's money for 90 days.
I'm sure if you are selling there for a year, restrictions would be lifted. If you look at it from eBay's point of view, there are so many scammers/criminals these days that they would be losing a ton of cash without the restrictions.
It's amazing in life how much scammers/criminals cost every person. Just one example out of 100's, the lock on your front door is to stop theft and the lock costs money
