i learn that bitcoin is created every 10 minutes and if block is created faster than 10 minutes, Difficulty will increase.
and study deeper, mining process is finding nonce that start 0 to increase 1 until finding hash value same or small rather than 'Target'
now, 2019-02-14, Block #562968 's nonce is 3,534,700,356.
it mean according this answer, it calculate 3GHash to create new block.
according to newest Mining Hardware ASICs, it says ASIC miner is calculating 14~16 TH/s. that does not make sense. PoW hash value is calculated 0.001s with this ASIC.
what i missed?
