@jrcornel as ever - you are cutting through the BS and making good points.
I think that people are generally fearful of what they don't understand. Arguments against bitcoin are not even that complicated. People do not want the status quo to be disrupted and therefore will definitely try and fearmonger about security, anonymity etc.
Let me know your thoughts on my recent blog post - I a think that Bitcoin's boom effectively means the end for altcoins in the next few months.
