please which is better,cryptonote or dash algorithm?
This question is similar to "which is better: punch cards or hard disks"
Cryptonote is simply technically superior. This is not so shill any coin out there, but DASH anon tech is based upon bitcoin crypto technology, which is not exactly suited for it. Cryptonote uses more advanced cryptographic tech which solves automatically the problem DASH tried to implement with a complicated system of masternodes and all that.
I admire dev running cryptonote coins,they are not a popular algo coins,some of the devs now are just bitcoin clone and wallet builder,their only aim is to get into as many exchanges as possible to unload their huge premine or collect a lot of monty through ico,we seldom see crypto note kind of coin doing this ..
