ZEC is far behind Dash, you can see that in the number of transactions (https://bitinfocharts.com/comparison/transactions-zec-dash.html), in the number of integrations, in the availability on exchanges, in the pure vision of its project.

I see ZEC as limited as Monero : only focussed on privacy in what is pretty much a niche market and oblivious to scalability, userfriendlyness,
developing additional use cases, preparing for mainstream adoption.

You sense that too or you would not be in this Dash forum, expressing your uncertainty and worry in that post of yours.
