New learning.
I just noticed this in the advertising section of the forum.
The Bitcoin software, network, and concept is called "Bitcoin" with a capitalized "B". Bitcoin currency units are called "bitcoins" with a lowercase "b" -- this is often abbreviated BTC.

Thank you.
That's really interesting. None could've thought of such a difference between the 'B' and 'b' in bitcoin. How about the forked coins of bitcoin be indicated. Whether those coins too have similar nomenclature or it doesn't have anything to do with 'B' and 'b'.
