In what direction ?  

It would be very helpful for litecoin price

It seems that BitFury started massive deployment of their LightFury script ASIC: https://bitcoinwisdom.com/litecoin/difficulty
They completed deployment of their 10MW DC in Georgia in 4 weeks, and they probably allocated some percentage of it for deployment of their script ASIC.

Nasty surprise to KNC and Titan buyers. It will get much worse.

Obviously I used an online calculator and it came to about %66. I used the Tradeblock site, which isn't set in stone with the output numbers, but I would definitely say they are a good approximate. Here is what I input for one SP30 starting in September.

Maximum profit only indicates $3630, and yea, I was high with the difficulty increase cause I'd rather have worse case numbers to make a decision on. I think if I spend over $5k on a mining rig and then have to spend $300/month to co-locate I'd want a better reward than $3k-$4k. For 6TH/s in September I think $5395 is too much right now, that's all. I'm hoping all the numbers are correct. The reason I kept the diff at 20 is because at that time there will probably be a slew of KNC Neptunes online, thousands of Antminer S3's and, another one called Rockminer?, and then of course Spondoolie's. That's a huge dent onto the network, and if you adjust that difficulty setting on that page it does change your max profit considerably. The lowest change in 4 months has been %10.66.

I've never been a risky person, so I hesitate, and sometimes I lose out. The best thing I ever did was buy a KNC Saturn and then bought 4 upgrade modules. That little guy is still chugging along. I think if my house had more electrical resources and didn't have to worry about cooling I'd have mining rigs all over the place. It is addicting.

Isn't Litefury just some small 55nm SHA miner developed by a 3rd party using old Bitfury chips?

Well, bitfury is king and anyone who underestimates him is always in for a bad surprise

I would like to get your professional opinion on this:

Bitfurys 55nm Asic uses "experimental low voltage transistors" and is apparently hand-routed.

Would their performance not benefit from die shrinks?

I would recommend this calculator:

It lets you set an increase per jump aswell as an amount by which this increase decreases. (Aswell as time to deployment etc.)

I think if my house had more electrical resources and didn't have to worry about cooling I'd have mining rigs all over the place. It is addicting.

As a side note I really don't see the point to estimate a diff jump decrease over time as time has proven many times it will not stabilize unless Mining chip designers stop making new ones with improved efficiency.

Tradeblock as most calculators uses a diff increase per month, instead bitcoinwisdom uses a more realistic simulation where you can set the diff increase per diff jump and even adjust time between jumps. For example this month we had a 25% jump and probably will have a 5% diff jump, that means a 31.25% monthly diff jump.
Obviously is a lot more precise to calculate both jumps that only one even if the monthly jump is the same a 31% jump at the start of the month is a lot worse than a 25% + 5% jumps that is worse than a 5% + 25% jumps.

So to get more realistic estimation use bitcoinwisdom or any calculator that calculates every single step instead of monthly jumps.

As a side note I really don't see the point to estimate a diff jump decrease over time as time has proven many times it will not stabilize unless Mining chip designers stop making new ones with improved efficiency.

So how do the tradeblock and bitcoinwisdom calculators differ  ?

Hadn't seen that calculator.

Thanks.

I asked my current co-location place about S3's and they said bring 'em on! As many as you want. All they need of course are power supplies sent to them and they'll hook them up on large bread racks they have there. And if I have a lot, they'll make a good deal.
