Dear Expert Miners,

 I am looking to invest up to $45,000 to $50,000 and looking to get profits up to $6500 to $8500, Electrical cost per KWT is not more than $0.9.
What I studied in last month that if I make the following than I can be reachable to this profit.

1, ASUS B250 MINING EXPERT.
2, WITH 13 PCS OF AMD RX 580 & 6 PCS NVIDIA 1070 OR 1080 OR MAY BE SOME OTHER SUITABLE
3, ALL OTHER ACCESSORIES

As mention above looking to make 6 devices like this. so please give expert suggestions.
 
THE OTHER MAIN THING I WANTED TO ASK IS "IS THERE ANY CHANCE THAT THESE CRYPTO CURRENCIES VANISHED?? OR THERE IS NO PROFIT IN MINING??"

THIS IS MY FIRST POST..
THANKS & REGARDS
