Wondering what the general consensus is here, are cubes and blades considered obsolete due to their power consumption?

Over got around 225ghs, running mainly cubes and blades, but I liked these products because they allowed me the freedom to "grow into" this hobby. Seems like the newer stuff you buy the whole rig and it's a bigger investment up front, as it should be. I liked how ASICminer always seemed to position their stuff as a "system"- blades tied into the backplane, and cubes have locking notches and rather good price point compared to similar offerings from BfL. I get the impression they are less desirable now though, is this mainly because of power consumption? Crazy how fast this hardware race moves... I'm still a bit surprised to see people coming into mining and dropping over $1k on a miner before learning the ropes...

They are obsolete the ghash watt ratio is so much more than bitmain chips. i still wonder why people bought these cubes

Might still be useful for alt SHA-256 coins but it's too late for BTC now

All alt sha256 are lower value than BTC, so , useless ...

They cubes were obsolete before they even came to market.

Im putting all my blades and cubes up for auction on eBay this week !! You only have maybe 4 weeks at the most befor they won't even cover the power cost .. Blades are still going for 150$-300$ each on eBay and the cubes are being sold for about 400$-600$ each..  Prices will drop like a rock in next few weeks.. Im going to try to sale all that I have running this week and recover anything i can even if its only 100$ per blade its better then nothing. I don't have many transactions on eBay so hopefully people will bid lol .......

I still maintain that success in this, being highly speculative, is based primarily on the future market value of the underlying output: BTC. If BTC keeps trending up towards $2k then it's a much different story than forecasting based on present value. The difference is when these are actually purchased with BTC, at that point then yes, the goal is to mine back as much as was spent. Cash for equipment has a slightly different model because the medium of exchange, I mean if a cube costs $600 USD and mines .2 BTC, but that .2 BTC ends up being worth $1,200 someday it's a win. If you spend .4 BTC to buy it, then the goal is to mine back at least .4 BTC... Some people might be running conversions on their cash purchases, but with something that fluctuates as wildly as BTC it doesn't make much sense to do that as the cost is remembered/recorded in the actual tender used.

The thinking is more would be accumulated, and there would be greater leverage on gains when picking the correct alt coin to trade against BTC. The trick is picking the correct alt coin, and the odds are stacked against someone doing that hence part of the risk/reward model that rewards largely, but less often, to those who take the most risk. Adding another layer of risk, speculating on emerging coins, is usually too much for most of us to stomach; I certainly don't want to bother, for me BTC is the risky one, and all the other coins I might as well play Satoshi Dice. But that might shift in two months depending on the price of BTC or my power costs... If this were a craps table and BTC were a pass line bet, all the alt coins are like the "hard way" bets, they have the potential to pay out higher, but the odds are against you on picking the right one. And value is relative, the idea is to trade against BTC or cash or whatever with the other coin, then through trade to obtain more than you could by mining directly. It's the same reason nations have imports and exports, they leverage the resources available to trade for greater amounts of things they lack resources to create and thus meet demand and achieve optimal profits.

I started dumping my cubes today on amazon/ebay. Now I'm only ordering equipment that's 200+ghz (mostly the antminers)

As long as it covers your electric costs its still profitable.

Hopefully the Bitcoin price is about to break out of this $1000 range, which might help us poor miners out.

I have no idea why people buy Butterfly 65nm and Cubes instead of 55nm Bitfury miners which are 25GH/25W normal and 45GH/70W overclocked (w/heatsink & fan).

I've got 270GH mining on 415W on cruddy 83% efficient PSU.

The Bitcoins it produces are worth 40x my power costs.
Always remember mining profit = how much you can beat your energy bill (not how any bitcoins you can make!)

I will take a couple at 100 if your dumping them.

But to play this game like a boss you need to dump the old technology during the golden window.

You should have sold on here.
What are your ebay links?
I have been slowly accumulating miners and sometimes good buys on older equipment as well.

Agreed. We've got increasing input cost and fixed production rate, which should create a shortage and prices go up if demand is steady, which depends on assuming no government regulations or special-cause events, intervention, etc... The cubes are still one of the only "low end" options right now, not everyone can jump in and spend $2k on a speculative venture. Hopefully the shift in input costs plays out as supply and demand theory state, in the past it always has, but it all depends on a free market system of decentralized trade without interference.

the cube is selling in taobao at 500 USD , and blade is 300 USD , I am running both via 750w server psu .  it took 3 days to ship to malaysia .

Here's my link to my eBay listing just so you all dont think im bull shit lol :)

I've bought a bunch of stuff of eBay befor but never sold anything so the big fat zero on my user name dont help getting bids lol Also theres like 50 listings for blades so its pretty bad competetion. If I dont get any bids I might post a listing on here for all my hashing power. I got 16 blades left and im still like not 100% sure if trying to sale now is the best idea but Im trying to save up funds to make a bigger investment in 1 th or larger miners when available for shipping.. (Not Pre Order) If I post on here I might try to find A trusted senior member as escrow...

Cool I will watch your ebay sale.
I'm waiting for my BTC to clear coinbase then I am buying some gear.
Canaryinthemine is a good person to use for escrow.
There is also a list on the board of trusted escrow people.
Are all of your miners blades?

No i got some cubes also but want to sale all my blades first . Thx for the watch, there's still couple days left on listing and I priced it lower then all the ones I seen on eBay so hopefully it will sale ..

Got a bid so looks like I will get at least 150$ for one blade. Going to post more listings after I get off work today. Going to list all the extra backplanes and power supply I have for Blades. Will update with links after I get them on eBay .. If i can make at least 2000$ for all my blades,backplanes, and power supplies should really help me stay in the mining game this year ..  :)

itemes list on ebay get cheaper week and week. i happy i cancel
it excellant so many money being spent for bitcoin

Huh?

I'm also selling my miners on eBay, but would prefer to sell here to avoid paypal.

V2 blade, backplane and power supply for .46btc.
http://www.ebay.com/itm/121263473797

I also have an anker hub, fan and 9 erupters for .17btc that I haven't listed yet.

If I could sell it all to one person, I'll sell it all for .6btc. UPS 3 day Select shipping included.

Blades are out, cubes and chili miners are on the way out, but still a good investment for a newbie.

- New ebay listings -

5 blades plus backplane,power supply, router and 5 Ethernet cables. 850$ on eBay would sale for 750$ bitcoin price PM me ....

How many Blades do you have?

A lot of what you are trying to say has merit namely, a scalable bitcoin rig has many advantages.  Eventually however, there needs to be a revolutionary change rather than an evolutionary one.

Currently I have my radar on for a 1TH/s miners that I can get in quantity.

you nailed it, hole in one... all the stuff coming out now is not the "game changing next step", the next major immediate Cube-killing difficulty jump (breakpoint) isn't gonna happen until the evolutionary stuff hits the street. Lots of people have been talking about the new rig coming out next week, and next week has been delayed for two months now lol. I'll probably just let my stuff mine away until those 1TH miners start to show up.

Yeah, obsolete - very old power-consuming ASICMINER tech

Most of the rigs hitting the street are already mining. (You think the manufacturers don't "test" them before they ship? ROFL.) There won't be any dramatic difficulty reset from any new miners shipping at this point. The jump from the first ASICs where we saw superexponential growth for a while was the only big jump that will ever happen, absent a massive move upward in price.

To answer the original question blades and cubes are not "obsolete" in the sense of no longer worth using. They make a lot more than their electricity cost, so at the right price they still have useful value. That will continue for a while (during which time they will continue to depreciate to scrap value, but nowhere near that now).

If you want the latest and greatest, they are far from that.

I got 13 left of 16 blades left , 4 backplanes and 3 power supplies ...  I've sold 3 blades just today on eBay..

Thank the lord for eBay. most miners would be out of business if it wasn't for the nice folk that buy at eBay :)

This is my last one, which is why I'm selling it with backplane and psu.
