So basically this method allows you to get tokens on this site completely for free and then withdraw them for real money Personally I used this yesterday and made $2200 in Bitcoin. This method is really easy to use, enjoy. PS: Please don't ask if the method is working, I literally tested it today. If it gets patched, I'm gonna remove this thread. Enjoy while it last. Guide:
This looks like a scam... That bitcoin "invoice" is more likely an address the bitcoins get sent to...
edit: I dont have time to look at that "exploit" more closely right now but what i think it does is it overwrites the real destination with address from that "exploit" which most likely is OP's bitcoin wallet. There is no reason to write the "exploit" the way it's written unless someone wants to hide its true purpose.
