Me, too. I like and need it, it has a big role in my life nowadays.
Regarding its use for the world, I think it is really needed by the world even if not all people can use it and want to have it today. We don't look at the current adoption or use right now, we should also think for the future. I am pretty sure that in the future, Bitcoin will be more needed and probably utilized by most people in the world. In addition, Bitcoin is created for a digital or electronic money, and it fits for modern life. With the adoption that is getting more massive, it may be fully adopted as a global currency in the future. IMHO
