Ok, it looks like the vote is working as designed.
And looking at the response, seems to me that Bitcoin enthusiast are still very positive about it eventhough the price doesn't seems to look good at this point.
How many times could be vote though? I refresh the page and you can vote again. Are there no limitations? Or at least 1 vote per 24 hours?
At the moment, no limitations due to not having an account login system(I prefer not to have a login system). I could store cookies to try to limit 1 vote per 24 hours but that could still be abused by users clearing their browser cache. I figure there isn't much to gain from users potentially abusing the voting system. Eventually, when there are more votes coming in, I'll probably reset all votes every 24 hours.
