I bought bitcoin because I am super curious what will happen when the last(*most of the btc) bitcoin is mined, and I want to own a small amount of it before that point, just to be involved with whatever happens next. I realize that's probably super super weird logic, never the less, here I am.
Yes, sorry I wasn't very clear, I didn't literally mean the last bitcoin, more.. most of the bitcoin, I was thinking the 2035-2040 timeline (~20years from now).
Most people I know have the same thought process. "It is probably nothing, but I'm going to put a tiny amount of money into it just in case to avoid losing out." When enough people do this, they themselves are giving Bitcoin the value it has.
