Connecting and starting miners takes just a few minutes.

Machine Operation

• De facto none. You turn on the machine and it mines. At most, you restart it.

Machine Noise

• Can be reduced by 98% (see soundproofing).

The Only Deciding Factor: Electricity Price

• If you have electricity at home cheaper than we have in housing = keep the machine at home.
• If you have more expensive electricity, put the machine in housing.

Simple.

In mining we've been since 2015 and over that time we've understood / discovered things that we didn't even suspect at the beginning (positives as well as risks of mining).

What is the WORST that can happen?

#1 Miner Won't Even Pay for Itself?

• It won't go according to plan and you won't earn 500% but only 230%? Or you'll end up at zero (only the price of the miner will be returned to you)? Or will you lose money?

But how much MAX. can you LOSE?

• Max. as much as the miner cost, right? (you pay 5000€ for the miner, but the machine will mine 0€?) Of course not. The machine's lifespan is approx. 5 years, it mines 24 hours a day, 5 years continuously, it's impossible for it to mine nothing in 5 years. So you definitely can't lose your entire investment.
• In those Worse Scenarios (huge crypto crashes) you would get back, for example, only half of the machine's price? That is, a loss of -50%? It won't please, but you have half of the investment back… + the value of the miner that you own.

How much MAX. can you EARN?

• 5-10-20-40x? Even such profits from mining have happened so far. Extremes like 30-40x we probably won't expect anymore, but 3-5-10-15x profits are more than realistic (it depends on how the crypto price grows and difficulty).

Asymmetric Investment

• Crypto/Mining are simply asymmetric investments. You risk, for example, a loss of 50%, but the potential profit is 300-500-1000%? So 1 to 6 up to 1 to 20. (You invest 2000€ and risk a loss of 1000€ for a profit of 6,000-20,000€).
• So what is more expensive? If You Start or Don't Start?
• If mining earns, for example, 6x and you won't mine = Your Missed Profit 6x (600%)?

Mining Earns More?

• + It applies that mining standardly Earns More than buying crypto on the exchange (and therefore during declines you have a smaller loss with mining than on the exchange). (If BTC rises 3x, mining earns, for example, 6x) (And if BTC falls 50%, with Mining you're, for example, at Zero, or in a slight loss (depends on difficulty)) + You have a physical machine in your hands that you can sell.

#2 Crypto Falls to Zero

• Very very unlikely, but anything is possible 🙂 Even one of the world's largest banks went bankrupt in 2008. But if you Don't Believe in crypto, Don't Go into Mining either. Simple. In crypto there are people who rather deal with how much the market will go up (and not whether it will go up), since the whole crypto is still literally in diapers. And neither BTC nor any other coin can disappear (it's not a company, it's a programmed source code.. it can't be canceled or turned off). But the coin's price can of course drop. That's why we recommend rather large stable coins.
• PS: It's not BTC but its technology (Blockchain) that is revolutionary (we recommend studying: why / what for Blockchain was created, how it is used in the economy, companies..)

#3 Miner Breaks Down

• That's why we've been doing warranty / post-warranty service for years (see question #5)

#4 Others:

• After purchase you find out it's not for you – return option.
• You send us money and won't see the miner? That's why personal pickup is possible. And see our History / 13x Why Us.
• You won't have a place to place the machine – that's why we have Data Centers (housing).

Big players own Thousands of Machines

• Why would big investors (even from SK-CZ but mainly America) invest millions/billions in data centers. (only in SK/CZ we have XY large farms (in each dozens to low hundreds of miners)) America – there are data centers with tens of thousands of machines (owned by multinational corporations). Why would they buy it if it doesn't earn? Why do investors who have been mining for 6-7-8 years still BUY More Miners? Anyway.. neither crypto nor mining Are For Everyone. Big profit also bigger risk.

CONCLUSION:

• The biggest risk in mining is simply the risk of crypto price drops. #1 But if you don't believe in crypto, don't go into mining either. #2 And if you believe in crypto, rather go into mining than buying on the exchange (if you have money for it), since mining earns more.

#1 Where is the Catch?

• How much the machine earns (output minus electricity = net profit and return) you can clearly see in the Profit Calculator. There is no catch behind it. What it shows there, the machine will really earn that much (deviation +-1.3%).
• But it's about today's profits (according to today's cryptocurrency price…).
• The alchemy is thus in how much the machine will earn tomorrow, the day after tomorrow, in a year, in 5 years.
• Tomorrow the coin price +10%, so the machine will earn +10% more than today. The day after tomorrow the coin price -10%, so the machine Will Earn -10%.
• In the calculator you thus see the machine's return, for example, 12 months, but the machine can actually return to you, for example, in 7 months or even in 15 months.
• (but the crypto price from a long-term perspective rises steeply so…)

#2 You Need a Few Thousand €

• On the exchange you can buy crypto even from 1€ (a small part of BTC)
• Miner prices are on average 5-10,000€.
• Therefore Mining is a privilege of the richer. Not everyone can afford it.
• And not everyone who has money has the Courage to go into it.

#3 Time for Studying / Finding Out

• Buying crypto takes a few minutes.
• You create an account, verify, deposit money with a card and buy.
• If you buy wrong, sell, buy other crypto..
• With mining but you buy a physical (and more expensive) machine, so you probably want to decide correctly right the first time.
• So before buying you'll study / find out / ask more – which miner to buy, how it works, what electricity, housing, startup..
• And Most People Don't Want That.
• Most people want to quickly do some action and so hastily buy all sorts of crypto, then find out they did stupidity, so sell it, buy other..

#Advantage for You:

• Mining thus requires Devoting a Few Hours, to understand what, where, how.
• But in the end it's only an advantage for you, because it will naturally force you to study mining and thanks to that you'll make better decisions than on the exchange, where you make quick unconsidered steps (because nothing prevents you from it).

CONCLUSION: Why doesn't everyone mine?

• You Need Money and Time at the start.
• Most people therefore have to settle for a less profitable option – buying crypto on the exchange.
• But whoever gets into it, higher profits await than they would achieve by buying crypto on the exchange.
• And at the same time lower risk (crypto price drop affects mining profits less than exchange investment; you own a physical machine, the machine can mine XY coins, mining earns even when crypto doesn't rise.. )

*Our technicians will explain / show / help you with everything.

1. Buy extra?

• 1x LAN cable (internet)
• Nothing more. No Coolers/PC/Ntb/Monitors.. nothing.
• The miner is a PC in itself, it runs by itself.
• (you need a PC / Notebook / Phone but only for the First 4 Minutes for the first startup of the miner – then the miner runs by itself)

2. Prepare?

1. if you want to have the miner at home, you need a separate space (since the miner hums) and check the internet connection (details in question no. #5)
2. create 2 accounts

3. What (2) ACCOUNTS to Create?

You need 2 (or just 1) account (creation in a few minutes):

1. Platform Nicehash.com works as a pool, wallet and exchange in one, so this 1 account is enough for everything.
2. If you want to mine via standard pool, you need to create a pool-account (where the whole mining takes place) and plus any Exchange or Wallet (HW/ SW/ Trezor/ Ledger.. any), where the mined coins will go to you – INFO.

Where to Buy / Sell Crypto for Euros?

• On the exchange (cheapest) – The world's largest exchanges: Binance.com, Kraken.com, Coinbase.com
• Deposits/ withdrawals from/to the exchange are Free.
• Fees for buying/selling crypto: mostly approx. 0.1%
• Or in Crypto-ATMs (higher fee, approx. 3-5%, but anonymously).

Connection is FREE From Us.

We'll start it and also Show How To Do It (full support before and after purchase).

• How to connect / control / Where you monitor profits, Where to store crypto / sell / without fees / anonymously ..
• (the whole connection is but very simple and takes on average 4 min.)

How to Connect [procedure]:

• #1 connect 2 cables (internet and electricity)
• #2 find the miner's IP address via the app and open it in the browser (Chrome etc..)
• #3 In this interface enter your crypto-wallet number, where the mined coins will go to you.
• Done. The miner starts up in a minute and starts mining (full guide HERE)
• Mined coins are credited to your account every 24 hours

Miner Operation:

The miner runs 24/7/365 by itself, without interventions – no operation. You do nothing. Everything you need:

• #1 Outage – If the miner accidentally goes down, just Restart it (1 click; settings remain).
• (in case of outage you will Automatically get an email, so you don't have to constantly monitor the miner)
• (outages are rare – machines often run whole months without outage)
• #2 Dust off – Depending on the environment where you have the miner, once every 2-5 months you can Blow off the Dust from the miner.

Can a Layman Handle It?

• Just like you, so do all the others buy a miner for the first time and so far no one has been found who couldn't handle it
• For clients we have technicians / support who will gladly help you with everything.

What Internet Do You Need?

Internet requirements are very very low.

• #1 Speed: 7 Mb/s (download, not upload) is enough for up to approx. 6 miners.
• (even slower internet in remote areas in SVK/CZ has approx. 20-30 Mb/s)
• #2 Response (latency / ping): max. 50ms
• *You can Check Your Internet HERE

Data Consumption:

• approx. 20 GB monthly per 1 miner
• (depends on the mined cryptocurrency, pool … )

Mining via Wi-Fi / Mobile Internet?

• Yes, it's possible. The miner doesn't accept Wi-Fi / Mobile internet directly.
• But just buy a simple extender for a few euros, which accepts Wi-Fi / Mobile Internet and transfers it to the LAN cable, which you connect to the miner.
• Simple and mainly functional solution that Doesn't Slow Down Profits/mining at all.

Noisiness

• Large (3kWh) miners are Relatively Noisy (70-75 db) – probably the biggest disadvantage of miners
• therefore a separate room or Noise Reduction Device is needed.
• Small machines (up to 700 Wh) are suitable even for the living room (small, quiet)

Cooling

• miners cool themselves fully
• external cooling you solve only with approx. 5 pcs and more (and depends on the size of the spaces)

Dustiness

• Conditions are similar to any electronics.
• Dust doesn't help, but it doesn't harm directly.
• When more dust settles on the miner's components, the miner will slightly increase the fan speeds to cool sufficiently.
• In a dustier environment, thus clean the miner once a month and that's it.

Humidity

• Max. humidity is specified for each miner, standardly 5-95%.
• So no special requirements (even basement is fine..).

Data Center

If you don't have spaces / have expensive electricity, you can place the miner in a data center (housing).

Housing – Details

We ourselves have in the office miners (Antminer S9), which mined for 6 years and still work at full capacity.

• And those are machines that were manufactured 6 years ago.
• Manufacturing quality is constantly increasing, so machines produced today should "survive" even longer.
• But we don't want to overhype it and therefore we still state lifespan "only" 4-6 years. Real tested lifespan (not just theoretical).

Does the machine's performance drop after years?

• No it doesn't drop.
• A miner with performance e.g. 100TH has 100TH even after 1, 2 or 5 years of mining.

Rather maybe You Mean ..:

• .. that difficulty (mining difficulty) grows and your 100TH miner will therefore gradually mine fewer coins?
• That's true yes. But the machine will have performance 100TH both at purchase and after 5 years of mining.

To difficulty:

• Difficulty grows when the crypto price grows long-term (PS: the same applies vice versa).
• In reality, therefore, your miner in X years will mine daily, for example, half as many coins as today, but the price of these coins will be, for example, 2-3-4x higher.
• Your total daily profit (in euros) will therefore be, for example, the same or higher than today (everything depends on the development of the coin price and difficulty).
• And The Same Vice Versa: If the coin price in history fell long-term, people disconnected from mining, thus the mining difficulty also fell and your 100TH Machine thus Mined More Coins (those coins but had a lower price on the exchange).

Complaints

• miners are built from production for 24/7/365 operation
• Failure rate (our statistics) is therefore only 1.3% (out of 100 machines we deal with repair only on 1.3 machine)
• If a problem occurs, you send the miner to us by courier and we'll take care of it.

1.3% is but an average for all sold brands.

• But we recommend buying Bitmain Antminers
• It's about the highest quality machines on the market and the number of complaints here is even lower (approx. 0.9%)

Post-Warranty Repairs – Cheap

• You buy a car for 10-20-30 thousand Euros, after a year it won't start.
• Does that mean it's completely scrap? No.
• For example, the starter went for a few tens of euros.
• The same is with miners.

Miner for 10,000€, Repair 50-150€

Every miner contains 4 main Components:

1. Motherboard 2. Power Supply 3. Fans 4. Three Mining ASIC Boards (on them together approx. 300 ASIC chips)

• Motherboard, power supply and fans in case of failure we replace whole (we don't repair – cheap items).
• The hashing board (main component) has on it Hundreds of micro Electro-Components – ASIC chips, resistors, sensors ..). And those cost approx. 1-20€ (always 1 or a few of them fail). More expensive is rather the work itself (repair)

• And therefore, even though miners cost thousands of euros, the vast majority of repairs are 40€ – 80€.
• The most expensive repair we've ever handled: 210€

Most Common Repairs:

• temperature / voltage sensor: ….. 1.5€
• ASIC chip: ….. 7-16€
• new motherboard ….. 35€-110€
• microchips like PIC, CTIF, MCU: ….. 1€-3€
• main 12 cm fan: ….. 14€
• 4 cm fan on power supply: ….. 7€
• cost for work (repair) on top: ….. 20€-110€

What All Coins can you Mine?

• Every ASIC miner is made for 1 algorithm (not for 1 cryptocurrency)
• And the vast majority of algorithms include dozens to hundreds of different coins, which you can thus mine with 1 miner.
• Exact List of Coins HERE, or in the description of the given miner [section Specification]

How to Switch the miner to Mining Another Cryptocurrency?

• In the miner just change the pool address and the wallet number where the mined coins are to go to you (takes 30 seconds).
• You can switch remotely (online), from anywhere in the world.
• Our technicians will show you how to do it.

Can I mine 2 coins at once?

• What sense does it make?
• If you mined 2 coins at once (half of the machine on one coin, the other half on the second), one of these coins is logically more profitable – and thus you only deprive yourself of profit.
• (at best the profits would be exactly the same for both coins meaning also the total profit the same).

Automatic Switching

• For example, pool Nicehash.com can automatically switch mining to the coin that is currently most profitable to mine with your machine.
• You don't have to monitor or switch anything – INFO HERE.

*For everything we have technicians / support. They'll show / advise you everything.

Where do you Monitor Profits .. ?

• Details about mining and the miner you see in the online interface (from anywhere in the world).
• How much the miner mined for you, machine performance (THs, MHs…), chip / motherboard temperatures, fan speeds..
• And remotely you can also control the miner (turn on / off / change mining to another coin)

Where do the Outputs Go to You?

• directly to your crypto-account (wallet or exchange)

How Often do You Get Outputs?

• Every 24 hours the mined coins are credited to your account.

1. You buy a miner
2. Monthly you pay electricity (at home or in data center)
3. For mining in mining pool the pool automatically deducts mostly 0.5 to 1% (depends on the pool)

That's all

You don't pay anything more to anyone anywhere for anything.

Then, if you want to sell crypto for Euros (on the exchange) – fees are tiny (approx. 0.1%).

Is Mining Worth It only with 1 Machine?

• It doesn't matter if you have 1, 10 or 500 machines.

For 10 miners:

• You pay exactly 10x more for 1 miner.
• They consume exactly 10x more electricity
• They also earn Exactly 10x more. They won't earn 11x more or 10.3x more (they earn exactly 10.0x more).

In euros, 10 machines of course earn more (60,000€ vs 6,000€) but your investment is also 10x higher. (also consumption etc..). Percentages but don't change.

• Annual profit with 1 miner = 120%
• Annual profit with 14 miners = 120%
• Annual profit with 327 miners = 120%

Is Mining Worth It? (in general)

• Simple, look at how much miners earn and you have the answer (output – electricity = profit).
• And what is more profitable – To Mine or Buy crypto on the exchange?

You don't want to mine altcoins (LTC, Zcash..) .. because you don't believe in them as much as in BTC?

However, BTC miners are the least profitable machines on the market.

Simple Solution, that Most People Use:

• #1 Buy a miner for Altcoins (because they earn more)
• #2 However Outputs can Go to You Directly in BTC.
• * 2 flies 1 blow (you mine what is more profitable, but you get directly BTC, which you believe in more).
• *This function is provided e.g. by pool Nicehash.com

Nicehash has 3 Great Functions:

1. Automatically Switches mining to the coin that is currently most profitable to mine with your machine (most machines can mine dozens of different coins – but you don't have to monitor or switch manually, Nicehash does it automatically).
2. Outputs in BTC – Nicehash pays out outputs always directly in BTC and thus you don't have to have xy wallet set up for XY coins. You only need a BTC wallet (and for this "change" to BTC you don't pay any fees).
3. Three in One – Nicehash is Pool, Wallet and Exchange in one – mined coins (BTC) you can hold right there (you don't need to set up an external wallet). +On Nicehash you can also trade them for other coins, or sell for EUR and send directly to Bank Account.

#5 Is it still Worth Mining?

And what earns more? Mining or Buying Crypto?

(at the time of writing the article:)

If you want to buy e.g. 1 LTC on the exchange, You Pay 60€

For mining 1 LTC You Pay 49€:

• 10€ = it costs you 4x Antminers L7 9050 in terms of 1 day (machine for 4600€; lifespan 5 years (1825 days))
• 39€ = it costs you electricity for 1 day (3260W/h x 24h x 4 miners x 0.125€ / kwh).

So operating miners for 1 day costs you 49€, but miners will mine for you crypto worth 60€ in 1 day (1 LTC)

• You invested 49€/day, earned 60€/day.
• In translation: You got crypto with 18% discount (or yield 22%)
• So you earned 22%/day even though the LTC price didn't rise even a cent today.

Therefore mining is always one step ahead of buying crypto on the exchange

(and these are current calculations, when it's the market bottom and thus outputs at the lowest values)
