Unless you get free (or almost free) electricity, I would not buy a mining rig for Dash. It has become a very competitive industrial process. It is very unlikely you will pay the rig off in a short time, and in the medium term, the hash rate will make your fancy new rig uneconomical.
Guys, I want to use Airbitz. What do u think? I read the article about it here I think it is easy...)
It is already 2019 but if you want to know what are the best miners in 2019 just participate in Blockchain life 2019 asia conference. It is the conference about mining and all best miners attend this event. Trust me
