How much exactly did this rig setup cost you? I'm sure that's over 20k dollars well I'd rather invest half of that money on proof of stake coins, running rigs will be pain in the ass everyday, there are other things to be worried about like electricity cost and heat too, fire break out can happen, it happened to me once when mining and not at home
i bought these 1,000,000won (korea)
about 18k usd.
it charged 1k USD for electrycity cost a month...
