John Doe and his GPUs can not make a profit anymore. Only John Trump and his larger investment can.
Bitcoins were only valid when anyone could make a profit, albeit small, and drive its economy.
Right not, it's elitist. As in, bad.
John Doe has left the building.
What is to stop people from making a profit now? Shouldn't all the old gpu miners just reinvest their profits from the pre ASIC days? What is to stop somebody new to bitcoins from buying an ASIC to start mining?
I don't understand the argument that asics are centralizing. Unless you mean short term, but that is short term.
