Payapal Purchase protection:
Here are a few examples of situations where an item doesn’t match the seller’s description: you purchased a book and got a DVD, you purchased a new item but got something that was used, you purchased 3 items but only got 2, the item was damaged during shipping, the item is missing major parts (that the seller didn’t disclose), or you purchased an authentic brand but got a knockoff instead. If the seller has accurately described an item, but you’re just not happy with it, that doesn’t qualify for Purchase Protection.
Most of the eligibility requirements for Purchase Protection are written above.
Purchase Protection does not cover certain kinds of purchases. These include: digital goods (intangible items), services, real estate, motorized vehicles (of any kind), custom made items, travel tickets, industrial machinery (for manufacturing), prepaid cards, or items that violate our policies or eBay’s policies (stuff that’s usually prohibited by law anyway). Purchase Protection also does not cover items that you purchase in person, or money you send to friends and family.
I think they would say that an ASIC btc miner is by definition, a custom made item. Wouldn't they? You know what's their policy about BTC...
This is even more true if the scammer cashes out immediately from their paypal account.
