"Hey guys, just got a PM about a possible 1k BTC sale for $45k. Not sure if it's legit, but the OP wants to negotiate. Does anyone have experience with deals like this or know a trustworthy way to verify the seller?"
"Dude, that's a huge price drop from the initial $50k you were asking a few days ago. I'm curious, what's the story behind the sudden sell-off? Care to share the reason?"
"Whoa, 1k BTC for $45k sounds like a decent price, but I'm not sure it's a steal considering the current market. Has anyone done business with this seller before? Also, what's the payment method?"
