1.Bitcoin itself is unregulated, everything around it is.
2.Bitcoin isn't anonymous, at least not right now.
3.Those who think Bitcoin is a scam have no idea of what Bitcoin stands for, it's not just about the coin, it's about the technology.
The third point is where our government think that it is a ponzi scheme and it will collapse or burst and the value will crash like anything. Thus till now they have not even legalized in our country and may not even do so considering it is not easily traceable and price can fall anytime and people can lose their money.
