Speculation/investing, learning more/unsure, trading, gambling, illegal physical goods, other goods, business, or work?
A mixture of all of them I should think, you could ask the same question to all of us even 2010/11 Legendary members.
I guess primarily we're all here to try & make a load of money.
That was the reason I was drawn into bitcoin any way, I mean the technology is pioneering, Satoshi is a genius but my main reason for entering the world of bitcoin is/was making money.
I think that goes for all of us, anybody that says different is probably a liar.
