I was doing my daily rounds through some of the pages and noticed on my pool info that the global hashrate had dropped.
Then I looked into it and it was significant. It looks like 25% of the network hashrate just up and disappeared.

https://blockchain.info/charts/hash-rate

Not sure where it went, I'm guessing some of it has to do with the price drop and higher difficulty that some of the equipment that became profitable again might have come offline.
Then I thought that's an odd level of everyone being on the same page. It also seems really high for it to just be the next batch of Miners getting ready to be shipped out.

Not that I'm complaining it is nice to see a difficulty adjustment in the red as opposed to +20. At least for now.

Everyone had a spot of very good luck the past few weeks. Now its time for a spot of horrible luck. Just like what happened in early 2016. Time to ask Roger for some handouts right now

Older gear  was turned off?


still looks high on info below

https://btc.com/stats/diff


507,082   2018-02-01 05:09:38   

506,016   2018-01-25 01:48:20


1,066 blocks in 7 days and 3 hours and 20 minutes


7 x 144 = 1008
3 x     6 =    18

2 x     1 =      2


1028 blocks would be 0%

1066/1028 = 1.03696 - 1 =  3.696%  jump  at the ½ point

I mine alt coins with https://simplemining.net...
I see BTC as the super highway and alt coins as taxis and trucks needed to move transactions.

That's what I figured at first to, but then thought that's highly coordinated unless it was a massive "museum mine" I've been looking at it throughout the night and it does seem to be recovering. It just seemed like a big swing to me for such a short time.

Sorry I can't check your link; work started blocking all pool related sites last week, quoting it as a not private connection.

EDIT: Yeah I saw that we are back on track for an increase, hoping it stays marginal.

Don't forget BTC forks. Bitmain could trigger this drop by themselves if they just switched a DC or two to BCH or whatever other forks they feel like today.

Well, a huge drop in hashrate in combination with these low BTC prices -can- mean one thing...

Bitmain is coming with some new mining gear soon. (And profit the max out of it?)
People sell their coins at very low prices to buy gear, Bitmains collect their BTC and hold till full future recover.

They have done it before Wink

I love how people just make the most random bullshit up so they can pile on the "whine about bitmain" bandwagon.

Bitmain isnt even accepting BTC....


The falling BTC price makes BCH more profitable to mine even if BCH prices havent moved. There are multiple switching pools out there that will move mass amounts of hashrate to BCH when it is more profitable.

Stop buying industrial miners, running them at home, and then complaining about the noise.

Well he's partly right, Bitmain is selling off older gear to help finance the new miner...the rest of it is garbage though.

Of course there are party's moving their hashrate, but cannot see this drop in hashrate back in BCH hashrate rise,
maybe it is just magically gone, but I don't think so. Gear pulled off? T9's and S9's sold earlier on their site?

We cann only guess, but I won't be surprised to see something new soon. Samsung rumors state 11\8nm so Bitmains will come up with something if this is a serious threat.

And when BTC is low and you need to sell to pay in BCH, you have to sell your BTC at low prices, can't call it anything else?
It is not whining, just taken some  seen actions in mind...

With them advertising T9's for sale with near immediate shipping, I wouldn't doubt if they're clearing out mines for new gear.  Who knows, the Samsung rumors don't name the Chinese partner.  With Bitmain already maxing out TSMC's manufacturing capabilities, it could be possible they have grown wealthy enough to team up with Samsung to produce future ASIC chips for mining.

Its true Bitmain doesn't accept BTC nowadays, but i can't really say i know what they are mining with it. It may not even be Bitmain, but they are the easy antagonist to bring up. They tend to have poor practices and i have poor experience with their support or them sending me dirty ass Antminer that was obviously being mined on.

You know I have heard people say this a few times but have never seen it in person. I have purchased well over 10k miners from bitmain and none of the ones sold as new have ever shown up dirty or used looking. The RMA returns are another subject but I have never looked at a "purchased new" miner and had it look anything other than brand new.

Have you started after the S4/S5 era? I wonder if it all started with them getting a couple "Second Hand S5's" mixed up with parts with refurb/new and then it started some sort of Myth repeated by ear over and over, with people forgetting how it really started.

A myth? an urban legend? In Crypto? nah... Smiley If I had a Satoshi for every evil plot bitmain has been accused of in this forum I'd be a whale.

I like all the theories and ideas, I'd have to say that maybe it has to do with some of the gear coming off the test benches and being shipped out. Whether it be Bitmain or Canaan; I don't really follow any of the other suppliers.

It might have just been some movement of gear through the Data center, or like some said mining some random fork for a while. It didn't look like it went to BCH at least not all of it, as I had them on the same graph.

Either way looks like it was fairly shortlived as it has swung back up to nearly where it was. We are also back on track for another Diff increase.


Sorry for the glimmer of hope  Wink
