Hello, I am trying to do in depth analysis using public data from 2016 on mining strategies. The main parameter here is how much profited coins to put towards upgrading the asics in any given month. Does anyone have any advice or data sources on this? I can share my results here in a post later. To summarize the public data used as input:

- btc price
- network difficulty
- network revenue
- available hardware efficiency (gh/j)

I'm finding estimating the hardware value at any given time to be difficult but I've been using a simple model of [ value = 12*(current revenue) ], also thought of as its roi on free electricity after a year.

My estimate from the past was that its better to hodl the coins in an uptrend and upgrade miners on a downtrend, but after looking at all the data and running simulations, I'm not really seeing that as clear.

Hello,

I am awaiting receipt of my S9i 14 Th/s which is due for delivery this week.

This will be my very first mining experience. (I look forward) 

Do you have any advice on the quality of the S9s?

Is an S9i deemed more reliable than an S9, S9J, S9K, or others?

Thank you in advance
Mickael

okay I will attempt to explain it as best I can. It is a long explanation.

Give me a minute to compose my thoughts.

Bitmain is the largest builder of gear.

Bitmain cut three deals this year.

With hashnest
with viabtc
with bitdeer.

I estimate they control more than 20% of the worlds hash in :

Eth
Btc
Bch
Ltc/Doge

They build good asic miners.
They were selling s19pros which mine btc and or bch for 2k before the rally
They were selling L3+ for 300 usd back in the day
They now make an Eth e9 and most likely it cost them under 3k to build it.

why is any of the above important?

simple they can have 200% of the miners needed to mine

BTC
BCH
LTC/DOGE
ETH

the gear is cheap for them. by not selling it to regular miners. they make mining cheaper for them selves and difficulty is lower for themseleves.

they then list gear with really long delivery dates and if mining profits for them are high they make them arrive later.

worse yet no one audits them.

so say they run 1 eth e9 miner to handle the eth contracts they have.

it makes 330 usd a day for 2800 watts

say they have an extra one and they run it making the same 330 usd for 2800 watts.


they use that 330 usd to buy btc.

and the 8 s19pro contracts that cost 3300 watts each are shut off.

they save 8 x 3300 watts. they pay the contracts with eth that purchased the btc.

they can juggle from btc to bch to eth to ltc/doge.

no one audits it.  this makes them pretty much unbeatable if you try to run a cloud mine against them.

i have 10 s17 pros doing 560th. the best way for me to profit is mine and cash out.

for me to do better i would need to do what bitmain is doing juggle the contracts around.

so rather then rent my 10 s17 out for a cloud i simply mine them.


thats the best way to explain it.

note i said bitmain juggles its contracts from gear to gear. i can not prove it.


but i can prove they if they chose to juggle the contracts like i say they do they have the ability to do it.

so they can do it if they want to and save lots of power and money if they do it.

only someone with extra cheap gear can do it.

and it only pays for a major builder to do it.

I also started lotto mining with ckpool recently after resurrecting my old Jalapeño. Next project is getting it and my node running on solar energy.

It could be a faulty control board, or a bad PSU, nobody here has a crystal ball, you need to provide more details, since you flashed the miner with different firmware it means you have access to the miner's GUI, get us the kernel log ( it could be called syslog or systemlog on your miner), also post a screenshot of your pool/worker details, you can hide any sensitive data if you wish.

I made this post in two categories; first to encourage the newbie and second to advice the old members.

For the newbie, I believe most of us are sharing in my wish. My wish to become a legend, a legend with so much merits and positive trust.  But dreams do not come true without hardwork.
First we must appreciate and accept our newbie status by showing the inclination to learn.
We should learn by keen observations, by reading through the posts of the old members, this will help pattern our attitude in the forum, it will also help us to grow with the norms and ethics of the forum.
By so doing our passion for the forum will be high, it is the passion that creates the way to success.

For the Old members, I will liken the forum to a building from foundation to roofing.
The building at the foundation stage does not make it less building, but it is the stage at which the engineer puts much efforts and expertise. Take the newbie as the foundation, help us grow, for if the foundation is wrongly laid, it will have a significant negative effects at the completion stage.

Congratulations to me for having an account in this forum, I am looking forward to a rapid and sustainable growth with your help.

Using a pool or software with low payout is not what is needed here cause mining with GT 710s and 1030s is never profitable if put the time spent into consideration except if the coin is newly created with future promising.

It better to get a cheap hardware miner than using the GPU this day thats the reason people don't use the equipment OP spoke of.

looking for buyer/buyers

Price 760$  with PSU.
Pm me or reply below
Escrow accepted (Minerjones recommended).

Oh yeah, sorry I didn't calculate it earlier, so Justin Drake rough estimate is not very far from the truth.
Considering 92~100 then it costs ~ 60-70 $ for 10⁹ (which he estimated 50$)
-Now next is really total Bitcoin current market volume is about 1 trillion USD???

I know its a long shot, but I was curious how often a solo miner solves a block?  Probably not a topic that would freely come up by the person solving it for anonymous purposes.

I was just doing some quick math and the odds are way up there-

For example, assume there are 170,000,000 TH/s out there right now.  If you had 5 newpac usb sticks overclocked to 100GH/s, that would be .5 TH/s.  Take the 170m and divide by the .5 and that is 340,000,000 blocks before you theoretically would ever solve one.   Divide that by 144 per day and we are talking 2.3 million days or ~6500 years.

Having said that, you have the same odds as anyone else, you could solve a block on the first try, or get 10 in a row, or never.

It is said that the large pools such as slushpool represent about 15% of all bitcoins mined per pool.  But how often do you think a solo miner solves a block on their own?  Any good stories or discussions on the topic?

Hello,

I am mining in BTC and then transfer them to Binance (when enough has accumulated) for withdrawal in USD.

Hi All

I mainly use S9/i's due to price and replacement of hash boards being relatively cheap.

I have had some i put in a pile to sell as they do not work or bring a whole S9 down (constant restarting etc), BUT then i have gone to use them weeks or months later and they are fine??

The ONLY thing i have done is cleaned them with a stiff  brush and them blasted them with contact cleaner.

I'm wondering if anyone has had any success with using an Ultrasonic Cleaner and the relevant fluid?

This 6.5l seems to accommodate a whole hash board plus i suspect the fluid would last a long time if you clean the boards as i explained above.

Anyone got any views/opinions on this?

Thanks

They still have the shop, but they rarely have gear available for us commoners...

You could also send an email to Bitmain and pray they answer you..

You can also see the resellers, like Blokforge, Eastshore...
