Hi I'd like to buy bitmain coupons worth $200, $350 and $420. If you have any of these, please get in touch so we can discuss a price. I am also on telegram as @plugwalk14.
I'm fairly sure that I have encountered something in the services section asking for a review about certain websites that is selling bitmain coupon for a big discount. However, I have a suspect that it might be a scam so just be careful.
Ok, I have found it:

I'm not connected on them whatsoever not endorsing them. Used your common sense and due diligence specially we all know that bitcoin transaction is irreversible.
