i just saw the antminer Z9 . and i wonder now about the decentralization for cryptocurrencies. some smart people will come and reply "everyone ccan buy Z9 = decentralization ". but this is bullShit. it still 1 company one point of failure . Antbleed , Backdoors. etc . just imagine if shitmain have a hidden backdoor inside each one of those miners . shitmain will control your money . 

i used to vote and fight for cryptocurrencies as it has lots of advantages over banks big one of these advantages was decentralization  but not anymore .  if one company  or two control our money then this will be totally scam and shity future  . i have 100s of banks in my country i can chose anyone of them , now only 1 company can control my money LOOOL .

if cryptocurrencies will continue like this without true decentralization then cryptocurrencies  are shit and SCAM .

true decentralization MUST avoid ASIC ( at least until we have lots of ASIC makers in different countries  )
