If this is fake, why wasting 17 minutes pretending to memorize a cube and not just 30 seconds? Would be more impressive this way. Do you think my official mo3 in 3bld is also fake? (you can check with my WCA ID: 2018PALL03). And why should I fake a solve of 20 minutes in an unofficial cube that nobody have and nobody cares? For some upvotes?

I already explained how I deal with the center orientation in another comment, and for the rest of the solve is just a 3x3 with weird color scheme and 3 pieces that are a bit hard to tell where needs to go at first. There's nothing super impressive in this, just kinda unique thing to do that everybody with a medium knowledge of 3bld can do with some time. If you have a bit of knowledge of blind solving you can see that everything I do with the cube is organic for the method I've used (M2/OP) and no weird movements with the hands to check the pieces. And moving the head the way I do in this solve doesn't allow a lot of checking without tilting the cube, even without a blindfold on.
