Those polls are rarely accurate especially at the edges (see https://news.ycombinator.com/item?id=5536734). I added a "5,000,001+" option just to see how many people will click it.
Yea I was thinking about that... an option that is so plainly impossible that it doesn't need to be considered (over 1/3 of all BTC does it). I imagine $1.5 million is just on the edge of plausibility for some adventurous, wealthy founders here.
Even if they are untruthful, there are surely multiple bitcoin millionaires from Hacker News. Bitcoin was announced here multiple times in the very early days.
