Charlie Lee (who, whatever you think of Litecoin, is well known and influential) was talking about how the instamine holds Dash back
But it doesn't 'hold it back'.
It has fought off every would be competitor there's been for nearly two years. (From X-Coin, Cloakcoin, Vericoin, Cryptonote, you name it - they all came here trolling all year long and saying "Drk/Dash will be gone in a month" now that <replace-with-your-coin-of-choice> is here).
Instead it became the third largest marketcap pure-currency crypto in the world.
It's been able to directly address and enhance monetary deficiencies in crypto rather than indirectly.
It is the only articulated blockchain protocol coin outside of distant clones like crave and as such has been able to lever that technology to incentivise and grow the network, start a decentralised governance protocol and acheive unsurpassed transaction performance for a proof of work blockchain.
It has a highly organised, focused and structured development effort which delivers and a roadmap to match.
...if thats what people call being "held back" then the rest of crypto's in shackles.
