let's get serious here , this crap will never overtake Litecoin.
Do you have a particular reason for this?
Litecoin has been around much longer and is seen by the community as being Bitcoin's silver. It's much more than just a coin, and what it contributes or doesn't is irrelevant. It's going to be tough to kick it off the pedestal people have put it on.
I disagree. I think coins that don't contribute anything will eventually die out. I think when it no longer contributes anything it will die out (such as scrypt not working anymore). Still it will require effort.
Darkcoin's anonymity features can be built on top of Litecoin. Darkcoin is horribly launched and premined trash.
