I'm sorry for your loss, but lesson learned, next time when using crypto or any other payment method you need to do your researches if the website is legit or not , even if you were paying with your credit card or PayPal you still losing money, thats sounds better to use PayPal and Open a case later , but if your order was a $1M order, you wait 10 days order not received and you open a case and wait for PayPal to verify and wait for seller reply. the thing to do is to avoid all shady websites. stay with trusted ones.
