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?
Unfortunately, like some people here I haven't had my first ever bitcoin. That is mainly because my previous earnings went to my expenses back when I lost my job. And then I put some to alts investment but just a small portion of it. Right now, I still have a long way to gain back what I spent and to add some to reach 1btc. But hopefully it will be sooner.
