I even dont know that using capital letter of B with bitcoin has a different meaning. Well, this is really new to me and thanks fot educating people here in the forum. Its nice to see a post like this, like it makes me smile for a reason. Now, Im more proud as a Bitcoiner. 
This is how we stay unique from others. Even a 'B' has got varied representation on the same word mentioned for different indications. Though some users have made fun of it, this is truly a new information to users who aren't that aware about bitcoin as well about its techncal functionalities.
