The smallest unit is Satoshi. When Satoshi Nakamoto designed Bitcoin, one Bitcoin can be divided into 8 decimal places, that is, the smallest unit is 0.00000001BTC. Now people use this smallest unit of Bitcoin to thank Satoshi Nakamoto for his creation and invention. It is called Satoshi, and the Chinese name is Cong. At the same time, the following divisions are also made: 100 satoshi = 1 microbit (μBTC or uBTC), 1000 microbits = 1 million bits (mBTC), 1000 million bits = 100 bit points (cBTC) = 1 bit coins, or 100 million Satoshi = 1 Bitcoin. From this clever division, we can see that if 1 Bitcoin is worth 1 million yuan, then 1 microbit is exactly 1 yuan, and then 1 satoshi is 1 cent.
