No cryptocurrency ever will be the money of the future because of volatility unless two things occur, they peg themselves to their fiat counterpart or they replace fiat, and Dash is no exception. Yes we all can make millions with crypto as an investment and store of value but forget about competing with Visa or Mastercard in daily transactions for basic commerce operations. No single merchant in the whole world will accept cryptos for their utility, they do right now because they are accepting an asset that grows in value over time despite the high friction it brings to simple transactions.
Somebody is working hard right now trying to crack that nut and Ether is enjoying some luck with the brainpower unleashed with contracts and tokens until someone finds the perfect solution by trial and error, then it will be too late for those who didn't want to see the elephant in the room.
Once a coin is adopted in all countries for their daily transactions it will be almost impossible to dethrone them. Resistance will be futile.
