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.

Bitcoin mining is now a specialized and very risky industry, just like gold mining. Amateur miners are unlikely to make much money, and may even lose money. Bitcoin is much more than just mining, though!

puts me on hold for buying.  since it could do  40watts a th on low and 50 watts a th on high.

It would make me not want to fully go to m10's

I am mostly m10's and s9's

much smaller then you  but still growing in solar power.

100kwatt array
300kwatt array

may be doing a 500kwatt array soon.

3) Never invest more than you can afford to lose
2)Not your keys not your coins.
1) be like JJG just DCA

I'm definitely holding off. I was on the verge of swapping out all of my T1's / 821's for T15's / S15's but when(if?) the release of these 2nd-gen comes about the prices for these will drop considerably. Don't want to pay 1k for something I could pay 400 for in a few months.
