Here all the coins three that you listed are not much better than Bitcoin is .
Here ripple can't get the better future in the future because the main reason is they have not provided any wallet to use for the users , we can only hold in exchange only :/ .
And in case of the ETH , here i made much profit but still I have some doubt about it , because how the admin of the ETH coin give the big amount as an compansation to the users of ETH who are stolen by the attackers at the exchange .
And in cash of dash i don't think that it is much simple then BTC because in  BTC we can also make private transaction whose can be easily deleted after confirmation of the payment automatically and also it is much easy to use and handle the private key of the address .
