Thinking of privacy coins like
Monero, do you think that they could ever rival or challenge Bitcoin in its position?
I think not.
Maybe Monero can reach $1000000 per coin at the end of 2016? Who knows...?
A leader of the Monero community and donator to this forum thought that Bitcoin would go to 1000000 USD/BTC in 2014:
Not only I believe it will go to $1M this year, I have not heard very many good arguments from anyone, what can hinder it

~CfA~
Never, just thinking if money is ever to challenge bitcoin. they should stand alone with their price and not take bitcoin became their base price. Like ETH a lot of people have the same question with this.
