If you want to buy a bunch of Bitmain coupons (not 1 here, 2 there, etc), message me.  I have the following for 90% off of the face value:
$65 x 403 coupons
$160 x 403 coupons
$250 x 403 coupons
$340 x 403 coupons

This is $328,445 in coupons in total.

I am good with escrow as long as it is a trusted member (OG Nasty, Phil, etc).
