Because this O is smaller than o, please read the previous post again explaining the difference in power-levels of small things vs big things.

Im sorry, but I cant comprehend instead of you, comprehension is something you have to do.

A quick idea how to comprehend faster, if PoW was Sybil-preventing, why does IOTA still require humans to peer with each other on a slack channel?

EDIT: some more, PoW, how much work do you think a 1W device with shitty CPU+"Jinn", can do and how much work can a 1 400W device do with specialized hardware? You know the answer but dont want to see it, orders of magnitude more - which means any single ASIC or FPGA, could outrun and double-spend many IoT devices. Which means, the Work that IoT controller puts into using IOTA, is wasted energy, its an oxymoron.
