I'm feeling like there should to come new "S9", like there was jump from S7 to S9...4th > 13-14TH... S9 is becoming obsolete..Unless you have free electricity...Or Bitcoin jumps...But you can't just wait for it to jump...Difficulty is increasing enormous speed...And new Dragonmint...is ONLY 2TH better then S9...We need crazy jump in tech again
