Holy fuck this thread has gotten so long the amount of massive brain injury is huge. Why can't people stop posting RANDOM SPECULATIVE NON SENSE. Wait for their prototypes which they said they will SHOW and happily CONFIRM before they take any preorder money.
Without them even showing or asking for money this thread has becone 42 pages long. Also, stop with your bullshit speculations on what will be profitable and what wont. All of the comments are based on flawed logic. They all assume higher difficulty at the same bitcoin price which is retarded.
The price of bitcoin could very well increase to $500,$750,$1000,$1000+ so arguing anything about profitability is just insane as there are so many variables.
