In a way you're right.  For example, with stocks, you CAN'T buy 1/2 a share, or 0.02 shares.  With coins you can.  So yes, Dash is in the $700 range, but you could buy $50 worth of it.

However, it depends on how you look at things from an investment point of view.  Lets say I want to run a masternode, but I only have $15K.  Tell me how to do a Dash masternode???  Or even PivX, for that matter.  When you run a masternode, you're looking for steady income.  Crown is steady as any of the others.  Heck, I just learned I can run a System Node now for under $1K or so.  Again, which stable coin can give me that, with constant updates, support, and new features???

If you're a trader, maybe you're right.  I come from the stock market world, so I know what you mean, and with how Dash has gone up in price this year, it's a great investment.  Then again, Crown did awesome as well.  Unless you think there is only room for 1 or 2 masternode coins, I don't see how you can rule out Crown being able to grow in the future, especially with its proven track record and dev team.  

Affordable masternode, strong dedicated team, steady growth.  Dash and PivX aren't better than Crown when all 3 criteria are your investment criteria.
