Let me interpret this a different way. You are saying we should keep our units, mine BTC to make enough to constantly upgrade our unit so that we can keep mining to constantly upgrade? So, you are looking at a complete loss of your initial payment and just hope to make enough coin to keep sending it to someone that treats customers like complete crap? That is not a future vision I share.
I'm saying that it's entirely your decision, like it was to buy the units. You take your chances and see if what''s on paper is better or worse than what you have.
I'm not defending them, but merely stating a point that there are no certainties here and that there are different ways looking at it. In the end some of those ways make more profit than others.
I was commenting to a poster who seemed to know how the outcome will be and stating it's not that simple, not to one asking: "What should I do".
