Most of them use it for online payment and few keep it as a long time investment with a great risk, by the way even I don't believe in any polls because most of the votes will be from people who don't use Bitcoin for anything rather than trading it for fiat

Most people are here just to murmur and increase their post count, maybe to get to higher rank or maybe to get paid a few cents for that comment, which is why it is not recommended to anyone to depend upon any numbers here, because most votes will come from the ones who have just heard and just copy and paste the comments from different users for the reasons mentioned in this post itself...
