do you bought it from bitmain ?
if so you can send the repair there if you found it a bad "good" and they fix it for you.

no matter what bitcoin going to reach unimaginable high better stick with bitcoin while you still can.

uda 1 minggu kenal bitcoin jika dulu gak malas- malasan mungkin bisa lebih kenal 1 tahun tapi uda deh rasanya masih belum terlambat cari rezeki.

i think you can go something MRR (miningrigrental) if you can't afford mining machine
