A better question: why is litecoin better than monero?
isn't dash better than monero, they shares the same thing, but dash is a more suited name for a coin than monero can even dream about
monero problem is its name really nothing else
and litecoin isn't better than monero, people are more attached to it for emotional reasons...
Uhm, that is simply not true. The technology behind monero is new and based on cryptonote, including a baseline anonymity feature. For example, you can't even know who has the most coins, or create a "rich-list". Moneros blockchain is not parsable.
It still is a preference not a X is better than Y, it is all up to the user and their needs. Monero just seems a bit better for illegal activity is what I take from that situation while Dash seems to want to be a digital cash.
