From the point of view of economics, what do you see the main problem with Dash?
Money needs to be a store of value, means of exchange and measure of value. What are the characteristics of money that Dash is lacking?
To be a store of value an asset must either be issued by an extremely powerful and relatively trustworthy central entity (USD) or be as close to trustless as possible (BTC XMR). Dash is exactly neither of these.
To be a means of exchange an asset should be in use aside from speculation. (USD BTC XMR) Not so much dash.
To be a measure of value? Just about anything fits that bill.
Dash is a centralized, pre-mined, ponzi scheme.
