Was at the office when a message pop on my Facebook messenger saying he is dewi from Indonesia that he is  interested in buying BTC worth $2000 I ask him why not buy through the wallet he is using, he said the wallet is not yet verified, I asked him again which wallet he is using he replied Binance, I smiled, I also asked him why did he think buying online is better he said because no kyc or verification need online and I ask him are you ready to risk it he boldly tell me yes. To cut the story short he was persuading me to send the BTC first before he make payment which I refuse, he even told me to send half of the BTC which he will make full payment  after I confirm payment i send the remaining BTC I also refuse, then he said he's going to send me $300 worth of  Etherume to show me how serious he is, I sent him my Etherume wallet and he made a deposit of $300 worth of Etherume. at the moment it was time for my presentation at the office so I went offline after the presentation I came online, I was seeing all sorts of pidgin local Nigeria insultive words.
that caught my attention how can an Indonesia citizen speak and write a pigeon local Nigeria insultive words then I decided not to refund him his Etherume for him to feel how others feel when they are being scammed.
Note__ scammers can go extra mile even by sending you money first in order to achieve what they need.
I have one question am I a scammer too or did I do  wrong by not sending him his Etherume back because after this incident my conscience has been beating me.
 stay safe.
