I decided to make more research on this educative topic.
Many of us don't know when to use the big and small letter of Bitcoin. And here I will differentiate the two though there are almost the same but they have different usage.
The CAPITAL "B" of the Bitcoin is the network protocol of the asset. In other words it is the whole system of bitcoin. When you are referring Bitcoin as a whole, you used the capital letter. Example. pooya87 uses Bitcoin network to send the coins (bitcoin) to philipma1957. The capital B is the protocol (the rules Bitcoin is governed) and moves from one wallet to another (the movement in the Blockchain)
Bitcoin: the network
Small Letter "b". The small letter "b" in bitcoin is used when referring to the currency or the coin. That is the unit of bitcoin you have is called as bitcoin with small letter. Examples. klarki gave 20 bitcoins to 1miau as birthday gift. CryptopreneurBrainboss sent 10 bitcoin to Mia Chloe to support orphanage.

bitcoin: The Currency/Coin
The uses of BTCBTC basically used for the currency or the coin but it use for the two. Bitcoin and bitcoin.
Igebotz has 100 BTC. Or Fillippone sent the coins on BTC network. The first sentence is the coin (currency) while the second sentence is the network.
