But literally speaking Satoshi nakamoto is a "saint " who literally forged the future transaction method and just disappeared
You will create arguments if you call Satoshi Nakamoto as a Saint, God, but if you call only as Satoshi or Satoshi Nakamoto, no argument will appear. I usually use the word Satoshi when I mention about Satoshi Nakamoto.
I recently just took some basic knowledge about crypto currencies and Defi that was when I actually acknowledged the fact
Bitcoin and Satoshi Nakamoto don't have anything to do with DeFi. Please stop trying to connect Bitcoin, Satoshi Nakamoto with DeFi. DeFi is more about altcoins and many altcoins don't have good quality. Connecting them with Bitcoin will make Bitcoin has low quality like altcoins.
