The "ebay bunnies" are already here too. Check some of the "feedback" in this or Cryptouniverse's thread. People actually start to make up excuses for Canaan and their distros to come up with insane prices like that.

I guess, this must be the 3rd stage of grief kicking in.

November carried 1280 EUR for 741. January comes up with 3800 EUR for 821, around 3 TH/s difference in efficiency. That's 300% the price for 37% up in efficiency.

If any of you welcomes this, you guys are damn idiots. Let's face it. The math is weak already at this point leaving aside anything which can actually happen in 10 months, even before those units were shipped, check: https://bitcointalk.org/index.php?topic=2445506.msg27722732#msg27722732

Why did Canaan stop manufacturing 741s and 761? "End of line" my ass. This is a basic money grab. And an obnoxious one. New "better" series, new price tag.
