Hardware with reasonable ROI?

[softworkz]

Hi,

this is my first post here on the forum.

I have read a lot about btc mining during the last weeks and did quite some research on hardware and return of invest calculations.

As a result I haven't found any mining hardware available at this time - be it new or used - that would generate a reasonable return of invest over any possible timespan.
Some ASIC miner specs may lead to a positive calculation if theses devices would be available today, but all of these devices have deferred delivery dates...

So my question to the experts here: Are my calculations correct?
Or is there any hardware available today - used or new - that I can buy now and that will generate some reasonable profit? (no matter if it's 500 or 5000$)

Thanks for your thoughts,

In my opinion, the only hardware that you can purchase now, have mining within two weeks, and have a reasonable chance of reaching ROI are Bitmain Antminers. 1.45BTC for 180-200 GH/s is just over $6/GH.

However, now that Hashfast, Cointerra, and Bitmine appear to be shipping, I would proceed with caution because a lot of hashing power will come online within the next three months...

If you are looking to make money, just buy BTC. You'll save yourself a lot of work, and the odds are that you'll make a good profit.

If you are looking to mine guess you like that sort of thing, research research research.  3 pieces of advice:
1) gpu's are great because they have a very good resale value.
2) for ASICs, if you want to break even in 2.5 / 3 months at least.  if it doesn't look like it will by then, don't get it
3) don't go for any preorders.  there is no point any more, and it is too risky.

Thanks a lot for your comments!

@kendog: I mostly agree. After all calculations the Antminer was my top 1 device. But even if I would get a used one for let's say 1500 USD, it doesn't look too good. Do you know the calculations from http://thegenesisblock.com/mining/ ?
I checked their calculation and it seems reasonable. The only thing I am not sue about is the projected difficulty increase - or the question if the dificulty increase from the last months can really be extrapolated into the future like they are doing...

In fact their projected difficulty increase is to steep that even Cointerra, Hashfast or Bitmine would not produce any ROI

@glendall:
1) sure, for litecoin might be an option.  Taking resale revenues into account makes the calculation look much better, especially compared to ASIC miners that may drop to a resale value of $0 quickly. But according to my calculations, the rentability of Litecoin GPU mining may become negative March or April (unless you don't pay for power consumption). Correct?

2) True

3) Would never do that. Especially not paying by bitcoins...

Perhaps the most profitable BTC business is to "invent" a new miner, create a cool website and accept preorders.

Or really get some engineeers to develop a new ASIC, accept preorders, build the devices and run them in your own data center.
Finally deliver them in the last month they seem profitable for people who cannot do some proper calculation...

what bitmaintech.com can trusted?? Do you have product from them??

1) gpu's are great because they have a very good resale value.

+1!!!  I was going to get some ASIC miners but with the current difficulty and the cost of the device, it was going to be a paperweight soon after it broke even.  Went the GPU route so I can mine anything.

If they came out with a 200GH scrypt based dedicated miner, I might plunk down for it, but until then, GPU's it is...

Good you did your calculations and indeed, they are correct. You are very unlikely to get ROI from any hardware you buy today.

Why buy used? New Antminers go for about $1200 (1.45 btc).

Why buy new if you can get a used one for 30% or more off?

Seriously, for miner, the price and delivery date is the most important.
Though the lifetime of a used unit maybe shorter, it is not really that important.

I bet most of those ASICs will be shut down when it is no longer profitable to be run, before they are no longer working.

[vpasic]

there is no hardware with reasonable ROI any more.

investing in gpu rig is also bad idea IMHO.
long time to make ROI and scrypt asic-s are behind the corner!
resell value of gpu-s???
I don't think so.
in the last six months, shitload of gpu-s was sold for mining purposes.
in about 3-6 months they will not be profitable any more shitload of people will start to sell them!
you can imagine how many of them will be for sale! there is no one to buy them!
if you feel lucky enough to sell yours between million of them for sale than play fucking lottery!
you think people will create some XY coin with XY algorithm to make these gpu-s running?
well think again.

invest in alpha-t asic

that's a pre-order right?

[botcoinExpress]

yes

It was bad time for mining in middle of autumn?, before litecoin rising up to almost 50$.
Now difficulty not rised so high as price is rised. Strange but difficulty of LTC not rising it all now.
But in this autumn price of radeon card was not so low.

[empoweoqwj]

yes

Which makes it very risky IMO. You don't know delivery date, LTC price when it arrives, if it will ever arrive, whether it will have any privately-funded ASIC competition when it does arrive etc.

We all know what the first bitcoin ASIC manufacturer was like with their pre-ordering delivery dates 

[acslackr5]

invest in alpha-t asic

When are they shipping?

[empoweoqwj]

invest in alpha-t asic

When are they shipping?

That's suggests "certainty" in pre-orders. The only question  that can asked is "when do they claim they will ship"

[astutiumRob]

So my question to the experts here: Are my calculations correct?

Yes.
