People only scam because they are incapable of purchasing the things they want, most scammers are kids who cannot legally get a decent job to fund their csgo case opening addiction. (I want my 300$ back)
Actually, there are other services where the other person cannot get a refund as well. Bank Transfer, Money Transfer (Western Union/MoneyGram/Similar), and Alipay. But to do Alipay, you really need to be working with Chinese companies/persons. If someone is going to trust you with BTC, no reason they can't with Money Transfer or Bank Transfer.
You see, the rare scamlet cave creatures cant handle the cold and can only handle the summer, they go out and schange the area for computers and computer parts, although the last years the scamlets havent been reproducing due to the admins on mpgh not allowing them to scam since scamming is their source of power, the 11Hundreads were the golden years for the scamlets as the caves were bigger and everyone was extremely stupid, but thene they couldint use computers to hide in their caves and scam, they had to get gems and stones with bird poop on them and tell people they were magical stones from Odin, 5846 B.C is the year that scientists have found out that the scamlets were created out of weird people wrom the east, There are scamlets and scamlurts, scamlurts are scamlets with more scamming knowlage since they dont go on hacking fourms and try to scam, they own huge chinese companies and ship toys and whatnot around the world, these scamlurts are usiually found in countries with slavery since its easier for them to make scamming material, noone likes scammer.
