Topic: what asic miners did you choose? (Read 104 times)

we call mining asic "gear", I hope that is clear enough by now.

The problem with your request is that you have a good amount of money, free power but 15kw is really too small, in order to fully utilize the free power aspect, you need to be using cheap gears that are less effienct, such as antminer S9s, but then with that small amount of power, you will only be able to have just about 10 of them, which is a total of 140th.

Including racks, wires, and all, that will be in the 7k range, which is nowhere near 60k, but then 140th is really not worth the efforts IMO, yes 10 S9s will get you 1.2k monthly based on today's prices, say you will spare $200 to buy replacement hash boards/PSUs, so maybe you net $1000 a month, but I think the current figures will be the best you will ever see, in other words, this 1k isn't sustained by any means.

the other approach would be getting efficient gears to get the maximum hashrate squeezed in those 15kw, but then you lose that "edge" of cheap power since those very effienct gears don't require much energy to run.

My pick would be somewhere in between, 40-50w/th gears will do, maybe a second-hand M20s, uses 48w/th , does 70th and costs about 5k, you can probably squeeze in 4 of these, the total cost should be in the 22-23k range, hashrate is about 300th, that's about 3k per month, you should assume that the average income for the next 2 years (assuming the asic won't die on you) will be half of that, if the price does not collapse, the difficulty will double, so any expectation above 50% of the current numbers is somehow wishful thinking, so 1.5k a month.

But then you said:


Mining isn't really a very long term business, it's not something you can retire on, I mean in a few years a few halvings will cut the rewards into pieces and there is no guarantee that either the transactions or the price will compensate that, mining is really just investing in BTC using a different model than exchanging cash to bitcoin.

So my humble opinion is that nobody should count on mining for their retirement plan, health care, student loan repayment, or anything that has no room for error, mining is a very risky business, it should be treated as an opportunity to maximize your gains in the short to mid-term and nothing more than that.

You could potentially turn 60k into 120k in 1-2 years if everything plays out well, but will you be making 60k a year mining bitcoin for the rest of your life? most certainly not.

Due to Bitcoin price increase, the miners you want to buy any unit with 100th+ is also increase in value because of the price massive price increase of bitcoin. It's not the actual price compared before.

That is why they say it's useless to mine BTC because the ROI takes too long to reach if you bought a sample Antminer s19 pro the price is around $10k which is overpriced actually compared last year.

So those who bought that gear early already get the ROI after the massive price increase. Bitcoin price is too volatile we don't know what could be the price in the future.
Those sellers and distributors of new gear only rely on the price of Bitcoin and profitability that is why the price of that gear always changes.


I wouldn't suggest you buy this new gear if you don't know what you doing it would be better to start reading this

And I agree on what stompix suggestion try to start buying with 2nd hand or used miner. You can get fast ROI on that machines compared on new ASIC miner.

He said people are considering mining bitcoin as useless, not bitcoin.


Again, read what he is saying:



Used gear, gear that is not new, second-hand gear, refurbished gear etc.
You buy right now a new S19pro at 100$/Th that earns you 30cents/th a day and in your case with no electricity cost, an ROI of 333 Days or you go for a used M21S or T3 you can get at 40$/Th and you ROI in 133 days (if the miner survives that long or if you don't end with a kinder surprise miner).

I'm pretty sure mikeywith can tell you some far more accurate prices on this, but as he said, it's a bit of math to be done when choosing what's best for you, not just buy the most powerful miner and that's it.

Oh, and a word of advice, before ordering from some random website that has available gear with lower prices than everyone else, ask on this forum if they are legit, there are hundreds of scams out there.

Useless? I think you have a LOT to learn... But you can always sell it, its your loss (in the future you will cry for having sold).

How much you have isn't as important as how much the electricity will cost. That's what matters in the end. Europe is too expensive, unless you find opportunity with renewable sources or wasted energy such as from a refinery or oil rig.

Thank you. I didn’t know exists one section for altcoins mine. I do a new post in this place


My idea is buy 6 miners of 100th/unit aprox. if i decide mine BTC. Problem is lot of people says mine BTC is useless now if you are not a professional business of mining. What do you think? I wish install one asic at my home and other 5 in my business

They have MicroBT Whatsminer M30S++ with 110T hashrate only this and the s19 pro from bitmain are miners with the highest hash rate?

What powerful miner exactly do you looking for?

Are you looking for ASIC miner that mines altcoin? Then this is not the right place to ask this you must go to altcoin mining section.

i´m looking that since time and i don´t know what to choose. I think mine bitcoin can be worst decision. Maybe ethereum is the easiest way

and i can´t find any powerful whatsminer to buy. I visit the websites where is announced to sell but all is selled.



energy cost: 0$

power reserved for asics:  15.000w in one place


used gears? i don´t understand that sorry


i´m confused because lot of people says the time for personal mining as ended, and it´s better buy altcoins or btc with this 60.000€, or other experts says: "The sad truth is that most newbies buy the wrong equipment for the wrong price at the worst possible time."


probably i have a bad future for  for health reasons, and i wish have a way to make money to make my life more easy. But it´s difficult make the correct decisions.

It's like asking someone what car to buy for 60k? when you ask the question as is, the answer will be of no benefit because nobody knows anything about your personal case, there are some factors that would determine the most suitable mining gear for every individual case, what is your power rate? how much capacity do you have? are you okay when used gears or not?

You need to list as many details as possible if you want an accurate answer.

It should depend on the profitability, if you are going to invest in ASIC then it would be better to research first which miner will give you profit

Here are some tools that you can check

In terms of durability then check MicroBT whatsminer.

Hi. I preparing to buy my asic miners to start. If you have 60.000€ to spend in asics, wich ones did you choose to mine? wich models exactly?


thank you
