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.
Why exactly Dash method of using it as a store of value is worse than Central bank or decentralization as BTC or XMR?
Dash is decentrilized at some extent. Perhaps not as much as Monero but definetely there are more than 1-2 different masternodes, aren't there.
How do you know what is the use case of Dash? They have decent amount of places you can use Dash last time I checked (a few months ago).
Bear in mind, also Dash is accepted by Trezor so it is easy to store them in a safe manner.
You call Dash premined, well also bitcoin can be called premined at some extent (Satoshi and the few early miners mined shitloads of coins).
If you call Dash a ponzi-scheme, so is bitcoin. You get payouts if you mine bitcoins in the same way you get payouts for running a masternode don't you?
