Hello,

If you experienced miners have the funds to purchase lets say a hypothetical 100 S9's, would you make the investment?  I ran the numbers for 100 S9's through this calculator https://tradeblock.com/bitcoin/mining with 0.08 for electricity, you wouldn't break even until sometime in the 2nd year.  And who knows what can happen then.  BTC could drop big time or not, no one knows.  So given the volatility of BTC, the rise in difficulty which causes a decrease in profit, would you make the investment/gamble if you have the funds today?

Thanks.

Short Answer: NO

Long Answer: While as efficient as the S9 may be, $.08 Electricity cost is just too high for comfortable, profitable, Bitcoin mining these days. Over the course of a year, you can expect difficulty to increase at least 25% (probably more). If BTC price increases that's great, but as BTC price increases, so does hahsrate and then difficulty.

One hundred S9 miners is a lot to manage, and keep functional if I am to believe what I read. Quite frankly I think I am better paid at my "Day Job".

Just my $.02.

The s9 breaks a lot so no.

I'd make the investment but also buy some sort of reliable resource of electricity that can continue and could be cheaper. This increases the initial cost but reduces the electrical cost to very low (obviously it'd be useful to start one on mains electricity just to ensure it works correctly). OR just buy somewhere with cheap enough electricity (less than 0.08USD as for it to be a good investment, you would want to ROI in less than a year).

Mining isn't actually very profitable anymore really, though the antminer S9 would be profitable with very cheap electricity.

S9's are out for a while now. I am pretty sure we are every close to S11's and if not something way better than S9's will pop up very soon.

If you are to mine, get only the lastest hardware. They get outdated pretty fast.

Thanks for the response guys.  It seems like I should hold off on the investment then unless I am able to buy cheaper electricity. 

I think no one should start at 100 S9 miners.

I suggest you get a few maybe 6.

 Buy some dps-2500 psu's
 Buy some 4k breakout boards
 Buy some cooling fans for the psu's

and mine with the six s-9's .

you would need 4 dps-2500 psu's

and you would need 2x 4k breakout boards

sixty pcie  cables

six Ethernet cables

an Ethernet switch.

a place to let them mine in.

Now if you mined with s-3's or s-5's they are weaker and use less power along with less cables.

If you used s-7's you are close to the same.

I am not sure how much you have mined.

Actually I have 20 S9s so far.  I've been running it for about 5 months now.  I was wondering if I should buy more or not.  I'm concerned that the price might drop and won't break even in one or two years.

Just make sure you don't buy the new crappy autotune frequency models, which leaves you with used ones..

I sent you a pm.
