in my defense lol last time I got scammed with 400$, I paid that through paypal. But again, never got the money back...I see your point, but you can choose who to do business with. 3 years on the forum with 1k messages, for examples.
Avoid crypto, or raise your requirement from sellers.
I never once paid here with crypto and I can count on one hand (one finger, actually) the times it prevented me from buying a service that I needed.
Scammers, when they attack they always think of the way out first, he probably would have sent that money to several more paypal accounts and cashed it out. Paypal on the other hand refuses taking into account most of the services/products offered in this platform so buyer has a very weak case from the start...
But again its better than crypto, atleast you have a fighting chance here
