RC4 wont save this coin, too much competition and not unique enough
You may be right, and I'd be the first one to acknowledge that, but if so then we're looking at the likely demise of the entire altcoin market with the exception of so called "2nd gens" like NxT and Etherium.
Anonymity was the last / only great opportunity for plugging any substantial gap in Bitcoin's feature set and DRK was/is the only real challenge in that market.
Sure there are others now, but the basis for their existence was opportunism on seeing an already rolling bandwagon. There's nowhere near as much mileage in that as there is from acting first. If DRK doesn't succeed in breaking through Litecoin's BTC trading ratio record (factored for coin supply) then none of the others will and neither are any future altcoins having a purely currency role likely to.
People tend to open their mouths and post whatever flippant comment comes of the top of their head according to the prevailing trading sentiment of the day, but if you stop and think about what you're saying then some profound implications flow from it.
