Not to mention the 11.56 difficulty rise in LTC.....this is getting "interesting' in the worst way.....flat LTC price more or less over the last months....more
scrypt miners out...like toasters................need some price action to compensate in some manner imho


Have not looked but what is it ...difficulty on LTC up over 30% and we have not seen the full push on A4's or L3's yet imho...

glad I waited to buy...again need a pump in price to offset this in scrypt pow and LTC as a specific notion....

I think Bitmain has extended warranties to 180 days.  I am hoping this miner falls under the 180 warranty.  I am sweating the reliability factor from Bitmain.  They have been making real junk in the current generation of miners. 

And the LTC difficulty just keeps rocketing!

Question to owners:

Which miner is integrated with ASIC? How stable is mining of different Scrypt coins (not LTC)?

Maybe I messed it but was there much before hand press about this new miner or just poof here we go? Does make me sad, I held out on the A4s , then decided to go for it then had a lot of lost mining with troubles ( which I still have on jig yet)  then poof a new magical beast appears. I got a lot of hopes for the A4, been pestering them over the driver have a few ideas, plus they are built pretty good, at least none have thermal pads with paste on them like all the A2 boards I had. Oh well as it goes ..

The L3 was just suddenly posted on the Bitmain Chinese site, and then noticed that they were all over the place on Alibaba, AliExpress, and even listed on "Deep In The Mines" site here in the US.  So if any announcements were made they were made to the Chinese market only.  I think everyone was surprised when this seemed to come out of nowhere.  

For me it was lucky timing as I was just about to start ordering some more A4's.  So I kind of got lucky.  You are right about the A4's.  They appear to be pretty well built and we have not seen hardware failures with those units.  If they can tweak the software to improve the hashing and features they have a solid miner.

If the L3 is reliable, it just about makes the Titan and A4's obsolete.  The efficiency improvements are just too big to ignore.  So if you are a scrypt miner you really don't have much choice and have to upgrade to remain profitable.

The L3 appears to be the game changer that the A4 promised to be early on.  I would love to see Inno come back now with a tweaked, modified A4 that can run at the hash rates they originally talked about in the early announcements of the A4 chip to give Bitmain a run for their money.  

I guess we will have to wait and see if that happens.  The current A4 really isn't competitive with the L3 at this point and I believe it should be.  What is holding it back?  Early tests with the A4 chip seemed to indicate low power use and really nice hash rates.  So between chips to the packaging and integration something is lost in translation.  Maybe it will have to come as an A6?      

Lets review that Hashflare Cloud mining contract:

$8.20 x 250Mhs = $2050 up front for a lifetime 250Mh/s contract.

Maintenance costs are 0.01 x 250 = $2.50 per day

Assuming you can get maintain a return of 0.00003 BTC per Mhs over your first year, you're earning (at today's BTC price) $820 x 250 x 0.00003 = $6.15 per day - $2.50 maintenance = $3.65 per day profit.

$2050 $3.65 = 561 days ROI, and at that time you will have spent $3452 to have mined 250 x 0.00003 x 561 = 4.2075 BTC

Taking that money now, you could buy $3452/$820 = 4.2097 BTC

As I've only accounted for the 1st years BTC returns (year 2 might average 0.000025 BTC/Mhs in year 2 if you're lucky), I think that given the choice of Cloud versus Buying an L3 and mining at home you'd have been better off with the third option of buying and holding a diverse basket of BTC, LTC, Monero, ZCash, ETH, etc and trading.

There's a few variables that can change this picture a lot, the diff of scrypt coins (which affects your raw mining output), the mined coin to BTC exchange rate (generally rises and falls with fiat BTC price), the BTC price itself and the efficiency/luck of pools you mine.

As a steadfast miner, the difference with buying miners is that a.) once ROI'd the only cost going forward is electricity ($0.075 Kw/h for me), and b.) they generally retain 25% of their purchase price after 3 years so the true ROI is only 75% of the purchase price.

L3 ROI > S9 ROI
Its the best invesment at the moment even with the increase in diff.
Nobody is going to raise the exchange rate only for you to have excess profits.

Also don't understand plp who buy A4 or now L3 and send them to mine LTC. Whole point is to mine crapcoins so you can get more profits. If wanna mine just one monocoin, then buy S9 and mine BTC directly.

Did your order actually ship?   Looks like a fair price from Nakamoto. I ordered from another supplier, got my tracking number, but then nothing happened for three days.  Hoping to get delivery this Tuesday.
