Now lets look at the altcoins. Some coins do make sense that its worth money because the have a purpose. Dash is digital cash so to me, thats like btc/litecoin. Monero on the hand is a privacy coin. So why is a privacy worth anything?
Imagine that you have a hidden camera at home which shoots you constantly and which has been installed by a stranger. You know that the camera is somewhere at your home, it constantly records you, but you don't know where it's been installed and how a stranger can use the video recordings of you. Will you be able to live a good life and feel good in such a case? Would you be ready to pay someone who knows how to find and turn off the camera? I think the answer is obvious.
Privacy does worth something now and definitely will cost a lot of money in the future.
Even Vitalik Buterin has recently made a statement that he's been wrong with his stance to privacy, he'd revised his attitude to it and became more pro-privacy than he'd been before -
