Monero and Dash are both good coins. I use both to make sure Im covered. No need to trash either one in my opinion. Anyway the market will decide which is better.
Dash is a scam. They instamined close to 2 million coins, said it was an accident, then proceeded to lower emissions to make an already egregious distribution worse. That's what they did. No market needs to decide that--facts will suffice.
