I don't understand what the scam is here. You said he sent you a script, so what is it he didn't do or send you? The chat log content doesn't clearly explain to me what went wrong.
I would explain that this man sent my friend a script (actually sold my friend a script) and told my friend to install it in my friend's vps to get more reward in the masternode (DNR coin).
My friend did follow that man's instruction and when my friend set up that scrip in vps and also sent his coin to this vps. The script sent some private key from vps to @tkh23 -scammer's IP. So all coins were taken and stolen.
In DNR discord channel, I saw admin also banned this man out of the channel as well ( due to of selling that kind of script, cheating people...)
This is also the big lesson learnt for my friend and all people. Dont trust anyone with any script with good marketing for you to have more profit.
thanks for your question.
Tam cheng.
