I think patience is the biggest obstacle that AM investors need to overcome. People act like putting together a 50 THs farm is nothing more than pre-ordering 100 baby-jets.
AM wouldn't be here if they didn't have their act together. FC has been planing expansion from the beginning and has been doing great.
The bears have been loud recently and have used this two weeks of lower hash-rate to get the lowest share price, but I don't think it will last long.
