Sorry for offtopic, but this is the only way to help you save your money (or btc).

This guy selling 19pcs of L3+ - nickname Qosi:

Pretending to live in Belgium, Antwerp
Doesnt accept escrow
Doesnt want to scan you his ID
Asks btc prior - nonsence
Asks btc for shipping - cash on delivery
After that says he found out its not possible to send it like cash on delivery and asks 1/2 of the whole amount and second 1/2 after delivery
This sounds extra scammy to me
Ive asked for photos of the goods
He send completely fake foto stolen from the internet and photoshoped there my name and date, there was even wrong miners on the photo

Im going to provide proofs here later today as Im busy now

This is just as a warning.
