"Completion" doesn't mean there will be zero updates in the meantime. The huge amount of new features can only be released bit by bit. The prototype for example shown in the demo was working today, not in 1 year.

Plus DASH is a massive improvement over most cryptocurrencies in it's current state already. Trolls actually admitted they love and envy the technology so much they wanna steal it and start "DASH Classic" LOL. Good luck, losers
