Stop shilling. And to have the galls to say something like Nano has the ability to take on Bitcoin just indicates that you very new to this market - and thus want to make a quick buck by shilling your random shitcoin. The thing which Bitcoin has, and that few others can match, is acceptability from a large swatch of investors and predictable security/emission schedule.
And, just fyi, Nano is not made of users. Go to its reddit and you will see everyone shilling it and having price targets on it. Stop giving such these weak arguments - most of us are in here for the money and don't give two hoots of the technology.
