3  Bitcoin / Mining speculation / Bitmain BM1397 2nd-Gen 7nm Chip on: February 18, 2019, 01:52:20 PM
Bitmain has announced that they have developed their 2nd-gen 7nm chip, operating at an efficiency of 30J/TH. Link to blog post: https://blog.bitmain.com/en/bitmain-announces-next-generation-7nm-asic-chip-for-sha256-mining-delivering-breakthrough-energy-efficiency/

A 28.6% jump in claimed efficiency is huge if this turns out to be true.

5  Alternate cryptocurrencies / Speculation (Altcoins) / Litecoin Difficulty Vs. Price on: June 26, 2018, 05:35:38 PM
With the continued drop in LTC-USD price, we're finally seeing sustained drops in LTC difficultly as many miners are starting to run at a loss. This could actually be a combination effect with some miners underclocking their machines to cope with the summer heat/increase their efficiency.

LTC difficulty is currently ~7.3% off its peak, with a further ~+5% (to 9.9M) decrease projected for the next retarget!

Assuming price stays below $100/LTC, how low do you think difficulty could drop? I'm thinking 9M is going to be the floor, as summer heat really starts to peak and those who kept their machines running in the hopes of a price pump start shutting them off.

Interesting to see how the difficulty kept exploding from March to the start of June, despite the pretty much sustained decrease in LTC price, as the result of Bitmain just s******g out units.

Data from BitInfo Charts shown below, with projected difficulty coming from Litecoin

7  Alternate cryptocurrencies / Mining (Altcoins) / Antminer L3++ on: April 17, 2018, 07:53:58 PM
So I was looking at the Bitmain store page just now and noticed that the L3+ is now called the L3++ and shipping the first week of May. No specs on it, other than that it may be higher than the L3+.

https://shop.bitmain.com/product/detail?pid=00020180417191824749h9o7tHqN06C6

Anyone have some details on this? Lower power consumption maybe?
