SFARDS Technology has successfully developed and produced the first FD-SOI 28nm SHA-256 (Bitcoin) and Scrypt (Litecoin) dual-mode mining chip SF3301, as we have previously reported. After more than one month evaluating, prototyping, and extreme-condition pressure testing, the first 28nm dual-mode miner, SFARDS SF100 is about to start mass production.

SF100 dual-mode miner has 24 SF3301 chips that support the following modes:
1. Dual mining mode, Bitcoin hashing power 1700 GHS + Litecoin hashing power 47 MHS, the power consumption at wall of whole miner is 960W.
2. Bitcoin single mining mode: Hashing power 1700 GHS, power consumption 770W.
3. Litecoin single mining mode: Hashing power 47 MHS, power consumption 180W.

With 0.45W/GHS + 3.8W/MHS, the power efficiency of SF100 is showing really good potential. It is also possible to overclock to certain extent (Sha-256: 2 THS, Scrypt: 55 MHS). Based on recent Bitcoin and Litecoin price, a dual-mode SF100’s revenue is similat to that of a to a 2.8-3.2 THS pure Bitcoin miner, which makes it equivalent to 0.3-0.34W/GHS power efficiency when it is dual mining. Taking June 19th price for instance, one SF100 generates 4.2 USD from Bitcoin and 3.8 USD from Litecoin, or a total 8 USD per day (without the costs for electricity deducted).

SFARDS Technology will start selling the SF100 dual-miner to public in July, though there is still no official end-user price announced and the first batch quantity is limited. The SF3301 dual-miner ASIC chips will be available for sale on August to people interested in using them in their own miner designs, again no pricing has been announced yet.

With the current situation on the crypto currency markets and especially the low exchange rate of the Litecoin it is no wonder that we are seeing another ASIC manufacturer cancelling their plans to release a new Scrypt ASIC Miner. The problem with these kinds of actions is that manufacturers are loosing users trust, even though they may try to compensate their customers in some way. Back when BitMain announced the pre-order for the L1, something new for them back then, we weren’t that happy and now we are also not very happy with the fact that BitMain waited up until now to announce they are cancelling the L1 when they were supposed to actually start shipping the finished product. Below you can find quoted the official announcement from BitMain about the discontinuation of Antminer L1 along with what options they offer to customers who have pre-ordered the miner:

Dear loyal customers,

The decision has been taken not to continue production of the Antminer L1

In response, all customers will be able to choose one of three options:
1) The original order value of $599 will be refunded at 105% value [$629] by bitcoin at current market rates. Customers will receive bitcoin payment.
2) The original order value of $599 will be refunded at 110% value [$659] by bitcoin at current market rates. This will be credited against any new S3/S4/C1 order placed in the web store.
3) The original order value of $599 will be credited at 115% value [$689] against an S5 order placed in the web store. This will be issued in the form of a 15 day coupon, each coupon valued [$344.5].

Please await an email info@bitmaintech.com for further instructions.

Though we are sorry that we do not deliver this time, it still turns out that buying L1 from BITMAIN is a very best way to earn more Litecoin.

Data Analysis: In the beginning of L1 sales, you only need to pay 115.86LTC to buy one L1 per the LTC/USD exchange rate 5.17 in the early September. However, you will get 193.22LTC under current LTC/USD exchange rate 3.1. And then plus extra 5% value, a total amount you get is 202.88LTC per unit. Return on investment is 75%. If you choose coupon compensation, Return on investment is 91%.

It is not very clear weather BitMain has already finished with the development and has actually produced some mining hardware or they are cancelling things before they have actually been finalized. The problem is that after ZeusMiner cancelled their Volcano miner and 3rd generation Scrypt ASICs and now the same happening with BitMain and their AntMiner L1 Scrypt ASIC things do not look that good for Litecoin and other Scrypt crypto currencies. The low exchange rate of LTC at the moment makes older Scrypt ASIC miners not very profitable to run due to their high power usage and with no newer generation more efficient miners announced to be coming soon things could get even worse.

ZeusMiner has officially announced that they are canceling the Volcano project for a 300 MHS Scrypt ASIC miner that was supposed to be released by the end of the year. This announcement does not cover only the Volcano miner, but also the GEN III upgrade boards that the company was offering as an option for December upgrade to customers with existing miners that were supposed to be based on the same new hardware. While pre-orders for hardware miners are something that has become quite risky and not many people are still interested in making such because of the lot of uncertainties about the price of LTC. Still the Volcano looked Ok, but the upgrade boards were actually more interesting for many people that have already bought older ZeusMiners as they were a good means to bring your old hardware up to date in a few months time when the initial hardware you bought may not be worth mining with anymore. However the people that actually did pre-order hardware were the ones wanting to get their hands on the Volcano miner sooner, the ones interested in the upgrade boards would probably have waited until they were released to order them directly.

The reason that ZeusMiner gives as to what lead to the decision to cancel the further development of the Volcano and the new chips is that apparently most of the people want to start mining now and not wait for hardware for about two more months. The current not so favorable market situation with crypto prices keeping low and the difficulty continuing to rise is apparently why they have decided to halt the production of Volcano and GEN III Chip Blades. The good news is that unlike many other ASIC manufacturers they did not use the money from pre-orders to fund the research and development of the new chips as according to ZeusMiner all funds, which had been required for the R&D and production of Volcano, have been taken out of their own pocket. The money which they have received from the Volcano pre-orders (USD, BTC, LTC) had been set aside in secured accounts from day 1 and is still available to be returned to customers. So there should be no problems with getting a refund, should you decide that is what you want, something that is way more important than to give false promises and intentionally delay or refuse to return money to customers even after failing to deliver on promises like we’ve seen from some companies already.

We have never been too keen on pre-orders of mining hardware and we’ve liked the fact that most of the Asian manufacturers of ASIC miners who were actually announcing products when they are already available for sale, unlike such companies from Europe or USA that love to take pre-oroders. Lately however we have seen that many of these Asian companies have also been tempted to offer pre-orders for hardware that is not yet ready for sale and that usually does not lead to good things as we’ve already seen. Companies usually tend to not fulfill their initial promises due to hardware production delays, issues with software and so on when they take pre-orders. So even if we are not too happy with the decision of ZeusMiner to stop the development of the new chips, they are at least doing it the right way – coming clean to users and offering an alternative or a full refund in a timely manner.


The people that have pre-ordered have two options now:

1. Transfer your Volcano/GEN III Blade order to ZeusHash with 10% discount and ZERO maintenance fees for 2 week. Discount is applied based on our Halloween Special. For example if you purchased 1 Volcano for $1,600 (plus shipping), you will be able to convert it to INSTANT ZeusHash HASHING POWER at $0.503 (1T – 9.99T range, $0.559 originally) per GHS or $ 11.691 (>1G, $12.99 originally) per MHS.

2. Refund of the FULL AMOUNT (USD/BTC/LTC) in the same way we have received your payment + 10 or 5 GHS on ZeusHash as FREE GIFT FOR YOU. All Volcano and chip blades customers will get an email from our CS team to confirm your option. If your order contains at least 1 Volcano, we will put 10 GHS into your ZeusHash account. If you ordered only Blades, 5 GHS will be given. All the transfers and refunds will be done within 2 WEEKS. If you purchased from one of our distributors, please contact our distributor for conversion/refund.

Reinvesting the money you might have spend for a pre-order into the ZeusHash cloud mining service may sound like a good idea to some people, but to others it seems it is not as they will be limited to mining only either LTC or BTC directly. With a physical ASIC miner in hand you have the options to mine many other alternative crypto coins and that is one of the biggest advantages compared to cloud mining with most such services. The good thing is that you can get a full refund of what you have actually paid and maybe invest the amount in another of the announced Scrypt ASIC miners available for pre-order as an alternative option, that is if you still want to give money ahead of time to someone else.

We already know that ZeusMiner is not making Bitcoin ASIC miners, however the company is also offering Bitcoin cloud hashrate for miners. To realize this feature they have partnered with some other ASIC manufacturers to supply them with the required hardware to back up the hashrate they sell to users. The same approach will probably be implemented for the LTC hashrate as well now that the company will not be finishing their next generation of chips as they have initially planned. We have asked ZeusMiner how they plan to back up their cloud service over time with faster and more energy efficient hardware and the answer we’ve got is that they are working with some partners using their expertise in chip and product design to further reduce cost as well as power consumption so that ZeusHash wouldn’t be affected. So we may soon see some more announcements for partnerships with other companies making Scrypt ASIC miners, and we are going to continue following the further development. Feel free to share your thoughts on the subject even if you have not pre-ordered a Volcano or an upgrade board with GEN III chips in the comments below.
