If Dash really is flawed and vulnerable, it should be easy to raise the funds to attack it while it is, by all accounts, young. Why wait for a juggernaut to get even larger... if anything, prove the flaws and in theory, crush the desire to hold it. There are countless rehashed arguments about the launch and masternodes and this and that. If you don't like the history, don't buy the coins. If you just heard about the launch (which is impressive given that it's now nearly 2 years old) and are displeased or feel betrayed, sell your coins. It's exhausting hearing the same shit over and over again. Masternodes, IX, blockchain voting, DS, etc all didn't exist for months after the initial launch.
Why would it be easy to raise the funds to attack dash? Is there a bounty? Is it substantial enough to pique people's interest? My guess is that it would have to be in the 5 to 6 figure range to adequately motivate an attacker (this is only guess). I'm a theoretical thinker, so I don't need bad things to happen before I see a bad outcome. My guess is that many in the Dash community aren't and will have to see the ship sunk to realize the ship was badly designed.
