It's the same guy that took down his false missleading video: "Zcash, Bitmains Gold Mine".

I'am not saying he is lying, but we should take it with caution ..... It's possible that Bitmain that the first shipped
units are indeed the "testing units" but i would like to have proof form an unbiased guy. That guy doesn't sound
to legit to me, but as said, it's possible.
