I've left a feedback on
SirZelmer's profile. May I ask why you trusted him with
BTC1.5 considering he's just a Full Member without any trusted feedback and on his last untrusted feedback he's being accused of scamming? Sorry to point out the obvious but you can always use escrow. If someone refuses using it then you can be sure he's trying to scam.
Probably you will need to post the whole conversion of further proof only if SirZelmer posts here with another version of the story. For the moment can you post the address where you were supposed to receive the coins along with the link to open it on the blockchain?
You are absolutely right. I am not terribly experience with forum trading, I was on a streak of successful trades and his profile seemed legit enough. I guess I let my guard down and I ignored the red flags, such as his way of addressing me. This is the first time I have a problem. Definitely a lesson to be learned here for me.
I was avoiding posting my Sia address to protect my identity a little bit. I will be happy to PM it to you if you want, and if really necessary, I can post it on here as well, but I'd rather not. Hope you understand.
