Yep, 2018 has been a very good year for Dash with regards to integrations and merchant adoption.
Price/market will catch up to that at some point.

For every investor there comes a time to evaluate the following :

* what are the achievements of the project i'm currently in ?
* what are the use cases of the project i'm currently in ?
* what is the vision of the project i'm currently in ?
* what is the roadmap of the project i'm currently in ?
* does the development team provide clear and accurate communication to its own community ?

If there are no clear answers to above questions, then that should form a red flag.
