I remember several years ago similar poll was made and i was surprised most of the users answered NO.
In case your answer is still NO, I'd like to know what is your main reason not to own one bitcoin?
EDIT2018:
In 2017 it was 51% YES / 49% NO.
I'll leave voting open and since we are no longer in 2017 I'll change the subject to "Do you own 1 Bitcoin?"
What is your main reason not to own one bitcoin? My main reason is, first im a bigginer here in cryptocurrency i dont how to read the graph in trading, but i try my best to earn 1 bitcoin this year by joining in signitures campaign
That's a long way to go, you cannot just make 1 btc by signature campaign as they don't really offer good amount of money.
Signature campaign offers small reward by making you promote their project or product through your signature, if you want big money you try to risk your money, though investing or trading.
