Let’s do some basic math.
To start mining with $15,000, you would need the following:
Motherboard MSI Z170A GAMING PRO CARBON - that supports 6–7 mining rig would cost $130.
Processor LGA1150 motherboard the Intel Celeron G1840 Processor and costs $56.
Power Supply Your system is going to be running 24/7 and using close to 1000 Watts of power non-stop, so you’ll want to drop some coin on a good model. So, you would need 80 PLUS Platinum rated power supply that is 1200W or greater. Enermax Platimax 1350W, Cost $240.
Let’s ignore, memory, monitor, keyboard, OS, Case etc.
Cost so far per mining rig= $130+$56+$240= $426
Video Cards AMD Radeon RX 470/480 and Radeon RX 570/580 video cards are all the rage right now when it comes to Ethereum mining, but they are extremely tough to find since they are all being bought to mine ether. Cost range $219 - $359.
7 Card Rig= $359*7= $2513
Cost per Mining rig in total= $426+$2513= $2939
So, with $15,000 you can have approx 5 rigs consisting of AMD Radeon RX 580 8G GDDR5 cards.
One card would generate= 22.5 mh approx
Hashes per rig= 22.5*7= 157.5 mh
Total Hashes 7 rigs= 157.5 * 5 = 788 mh
Now if we use Cryptocompare calculator with standard power consumption rates, this is what you should be getting APPROXIMATELY.
Which means that you will recover your $15,000 in about 9 months.
Now let’s see what you can get with trading.
Jul 16: ETH traded for $136. Imagine you bought with $15,000. Now you would be holding 110.3 ETH.
July 22: Sold for $219 (current rate) * 110.3 = $24155.7
Profit= 24155.7 - 15000= $9,155.7
Conclusion: Do you need one?
NOTE: Of course trading entails HIGH RISK.
