Bad Ceti!  Bad!  I've had the mermaid on ignore for years now, and you made me see something I must respond to.  It (the mermaid thing) claims that the reduction in total supply of coins effected how hard it was to mine back in March 2014.  This is not true.  The first time it had and effect was in January 2015, where there was a reduction of ~7% of rewards.  Ultimately, the reduction in rewards mirrors Bitcoin, only on a smoother scale.  It reduces 1/14 of payouts roughly each year and Bitcoin reduces by half every 4 years.  The calculations are basically the same after 4 years with Dash.  But regarding mining in March, 2 months after launch, there was no change caused by the vote to reduce mining rewards ~7% each year.
