got an idea guys, click on Bitsyncom's trust and give him a poor review:  https://bitcointalk.org/index.php?action=trust;u=68196

Who would want to buy MORE expensive chips?

The economic brick wall is 28nm.  20nm is beyond rediculously expensive for anyone who doesn't know their own fab (Intel, Samsung).  Nobody is predicting high availability or decent prices of 20nm wagers from any foundry in 2014 either. Nobody (not even Intel) is using 14nm yet, the technical challenges of 10nm haven't even been addresses.   Still even if 20/14/10nm is techincally available what matters in mining is the cost per hash and Bitcoin mining is almost perfectly parallel.  This means a 20nm chip is going to cost MORE than a 28nm one (everything else being the same) until the cost per transistor is lower on 20nm then 28nm.   Usually that takes 2-4 years from process start and it is taking longer and the end benefits are getting smaller (higher NRE, more delays, more complexity, more yield issues, and overall a shrinking gain on the prior process node).  So 20nm SHA-2 ASICs probably won't make sense even in 2015 or 2016 and 14nm isn't even on the map yet (2020?+).



That means for the convieable future 28nm is as good as it gets.  There may be more efficient 28nm designs but that would mean a brand new NRE cost and it would have to be a lot better to make sense (i.e. a company's new chip would need to be so much cheaper (MH/$ and MH/W) that even after a share of the NRE it added it is still a better deal that then existing design).  It remains to be seen if that will happen.  Regardless once everyone is on 28nm and shipping in volume, the market will become highly saturated and mining margins will be a small percentage over electrical cost of the most efficient miners.  Have a less efficient miner, have higher than normal electrical costs, paying for expensive datacenter space expect it to only be a question of how long before your net operating margin goes negative.  Really no different than GPU mining.  Those with excessive electrical costs or poorly though out rigs could only profit marginally when the price/difficulty was high and when it tanked they had to idle or mine at a loss.

DaFuq!?

I solved 4 blocks in a little over 24hrs!

Honest question about BTCGarden: I don't understand how their 192 GH/s miner is worth $10271(USD) when you can get 400+ GH/s for $6995(KNC) and $5600(HF).  Are they shipping in the next few days or something?

Well if one can provide photographic evidence. Check.

Reports from legitimate purchasers with photographic evidence at the time pf receipt of goods, as well as courier documents/customs dockets. Check.

Evidence that units were preconfigured to specific pools where 900BTC (approx equal to US$1m, of a an approx $1B currency, further directly manipulating it's overall supply) has accumulated to specific wallets within specific dates. Check.

I'd find it hard for a judge not to consider such empirical evidence.

Especially when further corroborated with the evidence that the manufacture of chips equal to all the community bulk orders in total was in fact in Bitsycom's possession from late June. Posted by one of their own design team, and a total blanket on any communication from those entrusted with the funds and orders for weeks subsequent, followed by continued ignorance of their existence and inconsistent excuses.

Not to mention continual promises to refund which never transpire, and an aggressive increase in global hashrate throughout he same period which cannot be solely attributed to another US based manufacturer with an awful track record of delivering anything.

EDIT: As I have been quite rightly corrected 900btc is not equal to US1m, yet is substantial. As such the pre-mining may be less significant in the supply of BTC, but holding or reselling the quantity of chips on order is not. That said I want Yifu to retain 'Hero' status, but this is beyond giving the benefit of doubt now.

everyone who participated all the way back to group 1 gets a coupon.
1:1 (i.e. if you bought 1 miner, you get 1 coupon.  if you bought 17, you get 17 coupons, bought a 100, you get 100 coupons).

what I don't know is how many have shipped to begin covering the remaining 70% of you.  so, once I have that info, I can publish a list and PM those who are entitled to coupons

EMC uses GBT, so --request-diff should be working for you in the current version of bfgminer.

If BFL is purposely slowing the Minirig line, to force big-money investors to switch their investment to the Monarch line, this would be very troubling.

See --request-diff (GBT only until 3.2.0, released any hour now...)

Crazy overpriced.. Someone who bought this machine now wouldnt see and ROI until 6 months at the rate the difficulty is raising..

No one cares for your pre-order nonsense, come back when you have something in hand and ready to ship.

I do think that a scheduled weekly announcement would be good both for Yifu and for us, even if it just says 'took time off, did nothing.'

I'm happy to announce that we have a USA assembly house available for this project. So anyone from USA can get there chips mounted there...

The chips and boards will be assembled at a top notch west cost facility. This will get things faster and cheaper for USA clients...

How did you have FPGA in your hand?  You obviously didn't trust them until they had delivered a product so what were those companies making prior to FPGAs?
