On mining pools all miners get rewarded with the analogous CPU they have used.
I don't know exactly how many satoshis will be generated on every block after 2100 but I know they will be very few. Imagine splitting 1 satoshi. How? Will the bitcoin community create the nakamotos?
1 satoshi = 1000 nakamotos for example. Too dumb question, tho, since we can't know a damn thing about that era. Some say that life will end after 2100 due to loss of natural supplies.
I think that way before 2100,at some point,Bitcoin mining will become unprofitable.What's the point of getting a 1 satoshi reward,when the Bitcoin price might never reach 1M or even 100K USD?
After 100 years,the Bitcoin price might be even lower than the current price.
After 100 years,the electricity costs might be way different than now-green energy might become really efficient and we might discover a source of endless cheap and clean energy.
What if this doesn't happen and electricity actually becomes more expensive?
To answer you question-yeah,one satoshi can be divided,if there's consensus in the BTC community for such fork.
