Do you pay attention to this while you are posting on the forum?

Absolutely, I think it's really important to distinguish the two, it always makes a point more clear.

It is writing style but I would choose the bitcoin and BTC.

There are derivatives: Bitcoin, BITCOIN, BTC and I think readers can understand what it is.

In orders of good, my choice will be:
- bitcoin
- BTC
- BTC.

I don't like Bitcoin or BITCOIN.

It's not just style, style means just a preference, while correct writing helps to avoid confusion. For example, without this convention, the phrase "Satoshi's Bitcoin" could mean either Satoshi's protocol and code, or Satoshi's coins that he mined in early days. Also, "BITCOIN" is never used, all upper case is usually understood as an equivalent of yelling in written speech.
