In for 1, let's see how this goes. :-)

The "Easy purchasing..." link to your store in the first post is broken. The one in the second post works just fine though.

I get a 404 when I access that page... I don't see the product listed for sale on the site yet either, so I don't know how this got ordered... Did they put it up temporarily and take it down again?

In for two shares, order #904, txid 033abfd0034437c85087e2c0b6141228d1d71f3ac1a7c2ad41fdb66e71b23b9f


Sincere apologies. I ordered a combined R17/R19 order without first reading this. Hope I haven't caused you too much work.

An extra 100Gh/s is pretty cool though

According to kncminer, they are supposed to start shipping today. I don't know how far along the queue we are, but hopefully it will ship within the next few days.

I'd like to know how long it took for the last Jupiter to go from shipping to delivery.

I completely agree. :-) And mining is fun, so I'm happy to do it as a hobby for a small loss.

Although if we were to sell the miner for 50% of the cost when done with it, it makes the (yes, likely very innacurate) predictions more palatable. Break-even could be achieved in under 90 days if we started mining 1 month from now. Assuming same values as before otherwise. But you're right, nobody knows what the difficulty is actually going to do.

Yes, that's true. I hadn't factored that in.

The most realistic mining calc I can find is the expert-mode one at http://www.coinish.com/calc/ which says that if we were to start hashing today, we'd likely break even in 50 days or so, taking difficulty adjustments of around ~2.8% per day into account.

Unfortunately we're not going to start hashing today, and that's where the problems arise. Adding a delay of 0.3 months into the calc, it puts the break-even at 100 days. Any later than that and it's not going to happen, unless the difficulty increases slow down, which is unlikely.

0.3 months is ~9 days. I'm not sure what the shipping status is of the Jupiters or how long they'll take to get from Sweden to the hosting facility, but I suspect it will be longer. Also, using a pool other than BTC Guild which takes 3% (and has too much hashing power for my taste) might help a little bit, but not much.

I'm bullish on BTC though, so I suspect (hope) we'll make back our dollar investment, just not our BTC one.

Mining is a hobby that _costs_ money at the moment. Hopefully most people on this sub will have done enough research to determine that for themselves.

One thing I'm fuzzy on is how having lots of hashing power helps in this attack. As I understand it:

- You send a transaction for x coins and no fee. It will get confirmed /eventually/, but not for a while.
- A dice is rolled before the transaction is confirmed.  (silly gambling site!)
- If you win, you win. You wait for the transaction to be confirmed so everyone agrees what happened.
- If you lose, you send another transaction for the same x coins. (This time /with/ a fee?)
- The transaction is confirmed first as it has a higher fee and therefore more chance of getting into a block. This invalidates the previous transaction, and your subsequent loss to the gambling site.

You don't need to solve a block for this to happen, so what is the benefit of having the hashing power?

I had figured the cart would have a stock level built in and automatically sell out when done, but I just tried adding 100 shares to my cart and it still let me so I guess not.

Oh well, hope I get some.

Orders 588, 590, 593 (sorry, I had to get BTC from a few sources)

It's still showing as "On Hold", despite 6 confirmations. Is this normal?

Replying with very skeptical interest.

It doesn't look like you're trying to raise anything like enough money to do a decent ASIC run. What are your actual plans? An FPGA conversion? If so, what kind of hashrate are you getting with your current FPGA prototype, as the results will be comparable?

You also don't mention anything about your background or the other people (if any) working on your project. Do you have the background to pull this off?

Wait... I've just re-checked your site and it's now pointing at a holding page. -- Not looking good.

I'm back in albeit slowly, but there's still no sign of my deposit in my account. Am I going to need to open a ticket on this?

I fail to see the point of CloudFlare's Always Online™ technology in this case. 

I can't get on the site at all now. :-(

I sent some BTC in a while ago (7 confirmations) and even though I can refresh my wallet page, albeit very slowly, I can't get it to show me my new balance. Hope this sorts itself out soon!

All up and running now. I think the cheapo powered hub I bought couldn't handle the power consumption for all 8 miners - some of the miners kept falling back to a solid green light. No biggie, I've split them across 2 computers for now until I can pick up a better hub - I've ordered a 4A one off Amazon that should hopefully do the job.

Trust left.

I missed the postie, so have to wait until tomorrow to collect from the depot now. All the lost hours! aieee 

  - thanks for being so efficient
