Re: Could the need of Bitcoin being more divisible lead to a hard fork?
If there's ever a need to make BTC more divisible, it will come to a consensus among developers, miners, and node operators alike. A hard fork would likely happen by that time, but it won't be as controversial .. Everything will go smoothly without issues (at least that's what I hope for). Who knows what would be of Bitcoin in the future? Just my thoughts 
learn some code and data structures
there are no decimals in code/data. its all smallest unit of sats
to break the smallest unit into 100x sub units. breaks the whole accounting system of bitcoin.
it would break many rules of supply, require changing how many halvenings occur, changing how many sharable units will ever be created.. a huge mess and tragedy to the supposed claims of certain rules that should not be touched
