Huge decline in Hashrate (50%) ~100 ExH/S

China is really stepping up its efforts to crack down on crypto mining operations.

not a china ban but a upgrade of miners and keeping hashrate down to avoid a difficulty jump they dont want the difficulty to be 50% higher than this time last year they are trying to keep it below 20Trillion .. and at time of writing this. i just checkede a couple pools. and the funny part is.. the pool 'btc.com' yesterday (17exa) had a equal amount of china/eu/us stratums finding blocks. but today(13exa). EU/US have not submitted any blocks meaning china was still mining but EU/US has not been mining https://pool.btc.com/pool-stats

to explain more detail imagine its costing you say out of 17exahash (not accurate split of hashrate. pencil numbers for demo) 4.25exa US at 12c/kw  ($1.2mill a day electric) 4.25exa EU at 16c/kw ($1.6mill a day electric) 8.5exa china at 4c/kw  ($800k a day electric) which pool do you switch off first (i done the math using s9 asics.) now imagine you switched out s9 for s19pro and you can have 4.25exa US ($723k electric) 4.25exa EU ($964k electric) 8.5exa china ($241k electric) you no longer need to earn $3.6m(100btc(16 blocks)) to break even with world wide coverage using S9 instead you only need to $1.8m(56btc(9 blocks)) to break even world wide with s19pro .. separate scenario. which can explain the lack of america block solvers in scenario pool above infact. if you just switch off US and EU. you only need to earn 1 block to break even. yep have 8.5exa in china and only need 1 block to break even.. easy. or have say 13exa in china and switzerland and only need 2 blocks to break even so why run american stratums knowing that its costing those miners more than they are earning remember on average electric prices of america.. its about a break even threshold of about $35k a btc to mine and break even. if price goes below $35k a btc then its not worth it to mine in america

You either don't know what 50% means or you don't know that the total bitcoin hashrate for the past 3 months has been about 130 EHS. You also seem to be incapable of looking at the hashrate stats which shows that hashrate for the most part has been pretty much the same with normal ups and downs for the past 9 months. Even if you bothered looking at the recent hashrate in June you can see that it has gone up from about 118 EHS to 140 EHS. On top of all that China doesn't even have 50% of the hashrate in total all around their vast country. Even if they banned bitcoin mining country wide (which they won't) the hashrate won't drop nearly that much.

Under the Chinese government's crackdown on Bitcoin mining farms, the Bitcoin mining hash rate is decreasing. In the future, the hash rate will recover and increase as miners will upgrade equipment and find a favorable place to continue mining. Information about a 50% drop in hash rate is incorrect. You can check it out at the following link https://www.blockchain.com/charts/hash-rate

china announced a crackdown of mining farms in coal power plant regions since 2014 mining farms have never set up farms in those locations. they had already decided to set up in regions of renewable and enjoy special electric price contracts in those regions because of renewables. thus. non-big-deal most of the hashrate volatility is hardware upgrading and also america not mining because the price is sub $35k so its not profitable to mine IN AMERICA hense the slushpool lack of US block solves when price was under $35k

Thanks, I used to think that Bitcoin mining factories were shrinking because of the government. So the Chinese bans we hear about now are just a repeat of the old laws they applied. Hardware upgrade is the main reason for the decrease in the Hash rate. I believe Bitcoin's hash rate and value will continue to set new ATHs. A good time to buy Bitcoin could be now.

I knew it the moment I saw one of your posts that this is going to be a day I will run into you on every damn topic. So, if you say that Chinese miners have abandoned those regions since 2014, can you please let us know where Bitmains's main farm is, where did they move when they "reportedly by you" leave Ordos? I guess nowhere since they've left in 2014 to be back in 2017! Second, if all those miners have left Inner Mongolia and Xinjiang why did this happen: Or is it possible that you don't trust data from btc.com now? Nobody is mining at Wikipedia prices Franky, nobody!!!!!! PS. I miss frodo!!!

okay once upon a time I ran a difficulty thread. others run it now. the reality is that : bitmain is god cannon innosilicon microbit are demi gods. the four companies basically are acting like opec and controlling the supply of gear. many say there is a chip shortage and that has slowed gear. but the s11 s15 s17 s17pro s17+ s17e s19 t15 t17 t17+ t17e are all dependent on very specific psu’s only supplied by bitmain since they can’t get chips to build and sell gear ⚙️ they simply refuse to supply replacement parts and all of us that have any of the gear i just mentioned dead in the water due to lack of replacement psu. cannon all oem bespoke psus took me 150 days to get a psu that was 50th lost for 5 months bitmain 300th off line dead psus. microbit 100 th off line dead psus so 450th offline and 1100th online. since this is the btc only section I will not mention what I did with gpus I purchased since I could not get asic psus oh I did buy some replacement psus which have all been used. so why do the companies not sell the psus. simple they all cloud mine and they fix their own gear. this is their edge since they can not sell gear due to lack of chips. this will not end until dec-feb maybe later.

Ya know, there is nothing special about miner PSU's, we just need information on the output voltage range, max current, and voltage adjustment scheme (analog 0-10v or digital signals) and then talk to Accropian, Delta, or one of the many other makers of custom PSU's to have replacements made. Would not be cheap but certainly doable...

Well, as long as it is not a permanent ban, I’m hopeful.

I did not know that! That is so shady and wrong, but that keeps them in control of supply like ya said.  No wonder they started switching to the integrated ones and made their custom ones...

100% agree with you. If I had some merits I would give you some. I have a contact which is specialized in refurbished PSUs. He is telling me exactly the same as you every day. If I look his business, I go to the conclusion that repairing PSUs is a VERY profitable job actually.

Actually it goes beyond the bespoke custom psu's listed above. ATX like corsair or seasonic or evga are not suppling the big psu's. all evga 1600 watts are out of stock https://www.evga.com/products/ProductList.aspx?type=10&family=Power+Supplies&chipset=1600+Watts as are all 1300 watts https://www.evga.com/products/ProductList.aspx?type=10&family=Power+Supplies&chipset=1300+Watts and 1200 watts https://www.evga.com/products/product.aspx?pn=220-P2-1200-X1 corsair 1600 watts out of stock https://www.corsair.com/us/en/Categories/Products/Power-Supply-Units/axi-series-config/p/CP-9020087-NA corsair 1500 watt out of stock https://www.corsair.com/us/en/Categories/Products/Power-Supply-Units/axi-series-config/p/CP-9020057-NA corsair 1200 watt out of stock https://www.corsair.com/us/en/Categories/Products/Power-Supply-Units/hxi-series-2017-config/p/CP-9020140-NA seasonic has  3x 1300 watt models https://seasonic.com/catalog/product_compare/index/ Top Dollar only resellers https://www.newegg.com/seasonic-prime-1300w-platinum-ssr-1300pd/p/N82E16817151214? https://www.newegg.com/seasonic-prime-gold-ssr-1300gd-1300w/p/N82E16817151208?

The 1200 / 1300 are available at many retail locations. The local Microcenter here on Long Island has them. The 1600 comes in and out of stock very quickly but I have seen them. Other then that, yeah you are 100% correct. There are some off brand ones at other retailers, but not something I would trust long term. -Dave

yeah the ATX can be found at steep prices from resellers. supply lines are crazy right now.

Probably from folks trying to find PSU's to power S9xx, Avalon 8-9's etc?

That or GPU rigs. Also, as the issue is the lack of many parts in general. And it's just creeping up. You just need a 400 watt unit for your PC for something, and it's sold out. So you buy the 500. I need a 500 and would be perfectly happy with a generic unit but you got it so I get the EVGA. Phil needs a 500W for a 3 card rig and wants the EVGA but it's sold out since I bought it, so he gets the 850. etc. In real life: I bought a 1000w PS for a clients massive drive array because the 850 that was overkill was sold out. I could have gone to another store or ordered it but I was there and just got it. Multiply that by 1000s of times and you have the situation we are in. -Dave

I have been selling used apw3++ on ebay at $111.11 and they have sold well. I got them in Dec 2018 new at wait for it $35 a Psu. I used them for 2.5 years. So yeah gpus are in short supply. We are having heat issues. I am parting out my s9s even though they make money. 123.45 a hash board tested to work 2 dead hash board at 111.11 So there are people wanting the gear

There is always someone who wants some gears, most of the time it's the noobs who can't do the math and think mining bitcoin will make them rich overnight, looking at the big picture, Bitcoin mining gears prices took a huge dive in China, today, S19 pro was sold for $7980, all the way down from 15k a few weeks ago, difficulty needs to go 12.5T or price to 60k for those who bought S19s at 15k to actually ROI within a year or so, and honestly I don't see either happening anytime soon. With that being said, if someone is fully positioned in fiat and wants to start mining, the current prices are far less risky, it might be a good idea to start accumulating gears now, especially that it seems like the sideways boring market is going to last for a few months, it's the best time for mining as it easily beats the buy-n-hodl model.
