Really dont understand why people buy these miners without doing research and then when daily returns drops to shat they say ...................I really really hope we can use these miners on another algo ? But in reality it just becomes an expensive heater. Bitmain does not change they flood whatever network they build miners for never thinking of their customer base. A3 was built to destroy competition which is what has happened and miners are helping them do this. American companies affected by the A3 include Obelisk and now DCRASIC. DCRASIC actually says they are afraid of a Bitmain attack which would cost them millions.
