Key indicator of long-term investors trust is the number of Masternodes.

And this number is growing:


(downtrend in the end of August is the V11 -> V12 protocol change)

What about current price... it is quite illusory - It's impossible to buy any significant amount at this price.
If you try to buy any significant amount (even a pair % of whole Masternode network) - it will grow up dramatically.

Current low price is just for some clever people who is accumulating DASH (from miners basically) for the next DASH "round"...

Dash - it is the good possibility for long-term investors, not for those ones who "should have time to sell one more altcoin before it will be ruined".
