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.
