Speaking from my own limited knowledge, the whole idea of btc is still a mystery to me till this day
why is it a mystery? i don’t think bitcoin is a mystery simply because it’s probably the most transparent system you will ever encounter in this world it operates under mathematics and codes and if you dedicate more of your time into understanding bitcoin it will not be a mystery anymore
Mystery for OP for sure because he/she still has not yet dived deeply into Bitcoin and based on the post it's just most of the core or history of Bitcoin like how it was started, so as new to these things, I could also say it is a mystery.
Still, it's good start to introduced in Bitcoin and could lead to more knowledge and learning about Bitcoin.
