It is a scam. I lost a couple of bucks trying to buy dogecoins. I opened a case with paypal.
Paypal responded:
Unfortunately, we are denying your claim because your purchase was for a
virtual, digital, or intangible item, which is not covered under PayPal
Purchase Protection.  We only cover claims involving physical items that
can be shipped and tracked.

Like it is a rocket science to use Dogecoin blockchain explorer
