Helium Mining

A good starter of the actual mining process and how it is calculated is documented here

Helium Manufacturers

What’s the best one to buy? Vosk covers it here

What’s the difference between them? Vosk addresses it here

Please use the following links to support Voskcoin and our community. Nebra , Bobcat , RAK .

Each hotspot vendor will provide everything you need to get your first miner up and running. One thing to note is that hotspot miners come with different frequency bands. Please make sure you are picking the correct selection for your region.

A list of each vendor and how many Helium miners are deployed is listed here


Currently still (11 May 2021) recommended option according to Vosk. This is because they have proven delivery records and their difficult payment option (using mugglepay) discourages a lot of would-be-buyers.

  • Order link
  • The easiest option is to pay in USDT/USDC when directed to mugglepay to pay.
  • You can purchase USDC/USDT immediately and withdraw with crypto.com - see Vosk’s video here or this VoskTalk writeup with screenshots / A Mugglepay Howto

LongAP appears to be a new (however licensed) manufacturer for Helium Miners. They are not currently taking any orders.

  • Website here
  • Expectation update for EU deliveries published on 5 May 2021:

“Just to set some expectations, we were approved a little over 2,5 weeks ago. Since then we have been trying to do magic by getting hotspots produced as soon as possible. This is a best-effort approach for all parties involved, which makes it impossible to get reliable estimates in terms of date of shipping. However we still aim for end of may beginning of june. The first small batch of hotspots just rolled of the production line. We are now getting ready to test these gateways to validate their function and performance. This takes time, but we want to be sure that our gateways actually meet our expectations.”


Another/Possible Helium manufacturer, not yet open for ordering

  • Page here
  • Their Helium application which gives some company background on Github is here (not HIP-19 approved yet)
  • Expect approximate cost of £300
  • Will accept Credit/Debit payments

Smart Mimic / Finestra Mine

A vendor who already sells a few LoRa gateways and sensors who appears to want to create a miner.

  • Their HIP19 application is here
  • No website yet

Helium Inc (OG)

The original Helium Miner manufactured by Helium is no longer for sale.

Miner Placement

There are various things to consider when positioning your miner and maximising earning potential. Considering that Helium operates on a Proof-of-Coverage algorithm, placing your miner in a location where it can communicate with other miners is the goal. The more hotspots it can communicate within a specific range, the higher probability of earning more coin over time.

Range is important. On paper, it is advised to space miners 300 meters apart from each other. With that said, it has been reported that if line of sight is too good, 300-350 meters can potentially be too close. If miners are too close, Witnessing can become invalidated, resulting in reduced reward pay-outs. Note that all vendor’s default antennas are good for several miles of range assuming no obstructions in line of sight.

This is why you do not see mobile phone masts every block, it does not expand network coverage in a optimal way. Do not cluster.

To get a visual representation of how your exact location may communicate with neighboring hotspots, please check out Helium Place . Input your address to review the sweet spot range. Your hotspot miner will be the black dot. Any additional miner that is within the red-colored heat map is considered an “invalid witness zone”.

  • Vosk answers ‘How many Helium miners can I have in my house?’ in this 11 May 2021 video

How much will I make?

Please understand that the current hotspot population is growing by the day. What may be virgin territory today could be a strong hotspot region over time.

If you are curious as to if a desired location (whether it be your residence or a family friends) will be profitable, please use Helium Explorer . All you need to do is type in your city, and a list of active hotspots will generate.

Click on the 3 word seed phrase to open that hotspot account. From here, you’ll see a map of it’s connections, 24 hour/prior 24 hour and 30 day/prior 30 day payouts, the profit % change, along with witness and nearby hotspot information. This resource is the best tool for gauging approximate profitability in your area.

If you reviewed your territory and noticed there are no neighboring hotspots near your location, what is the next best option? Time to phone a family or friend! A plausible option is to let a fellow contact “host” your hotspot miner. That way, you are maximizing your miners profitability. I’ll go over this more later.

How does seeing more miners increase my earnings?

@Toby’s example:


Just to let you all know my scenario and what rewards looks like here is my setups in stage 1 2 and 3 (Stage 1 = 1 hotspot, stage 2 = 2 hotspots etc)

Week 1-10 average 1.5
Week 11-13 average 11
Week 14 36

(Numbers = HNT)
Orange lines = Witness

  • A video discussing this as well, here
  • Vosk discusses witnessing here (9 May 2021)

How do I setup my miner?

It takes about 5 mins, turn it on download the app on your phone, bluetooth search for it, pair it up assert location on the map on your phone connect to WiFi or Ethernet and boom done.
Video tutorial here

Vosk runs through it here as well

Antenna Placement

Antenna Strengths

Vosk answers ‘What is the best antenna for Helium hotspot miners’ here

As mentioned, the standard antennas are GREAT - 10km+ in NYC has been achieved by a discord member as an example here -

(RAK v2 unit at 30ft elevation)

This image best describes what higher dbi antennas do:

  • Keep in mind, lower dBi antennas have more vertical range and less horizontal range. Higher ones have less vertical range and more horizontal range. Find a good balance that hits your nearby hotspots.
  • Careful with 8dbi or you will overshoot hotspots that are close to you and won’t witness/challenge them
  • Higher gain does not mean better or stronger all it means is that it’s more directed. Think of it like a flashlight or a garden hose. The more focused the light becomes the more direct the light goes
  • Antenna are environment dependent. If it’s in an urban environment a higher gain is not good you need a lower gain. If you are in open area trying reach specific point in an area than a higher gain is better
  • Antenna gain is just for penetration through buildings, trees etc. Your better sticking a 3dbi high up. and a 5.8 on ground for example
  • Angle of elevation also matters. If you mount a long range (narrrow beam) antenna on a high elevation and all the other miners are at a lower elevation your signal will just go right over the other miners and not link up. So in the picture with the two cars a 3dbi antenna will reach the other car but the 6dbi one will not since the signal just goes right over the other car.
  • Keep your antenna cable runs low - a handy refference for signal loss over cable lengths here
  • Jimmy is Promo discussing antennas here



  • All manufacturer units support WiFi or Ethernet
  • Expect to use approx. 20-40GB of traffic per month for your miner, this will reduce once validators go online, reference
  • Ensure you forward TCP port 44158 to your miner from the internet to ensure your miner does not appear as ‘relayed’ (more info here)


What about the security of these miners?

  • See Helium’s knowledge article here
  • As with most IoT devices technical peeps tend to put these devices on a segregated network segment

What's the future for Helium & HNT?

  • 5G
  • Topical video link (bullish speculation of $80-100 USD per HNT)

What about halving?

In a halving you earn half of the rewards you were before yes. and with more miners that reduces the total amount paid per hotspot down yes but typically since its harder to get said coins price increases.

I heard the halving might be postponed?

No, not confirmed.

  • There is a reddit thread here
  • This dude talks about it here

What about more miners coming online?

You make more money mining with more miners near you vs none, it’s not like normal mining. Video discussing it here.

Is it safe?

Concerned about safety of the miners?

  • Yes, as safe as a cordless phone
  • See this

Which miner should I get?

Since all miners perform the same, you should get the miner that arrives in a timeframe you can cope with at a cost you are willing to depart with.

Which region frequency should I get?

See https://whatheliumregion.xyz/ another list here


But I want two miners within 300m?

Okay, however they will not witness each other which means reduced earnings. See Miner Placement for more.

Why does 1 witness give me 0.5 reward?

Hotspots who only have 1 witness has a 0.5 reward scale, read about HIP17 here

No hotspots are around me?

I am alone / no hotspots/miners are around me, closest thing is 40 miles away, what do I do?

  • Buying more than 1 miner and placing it closeby (but more than 350m away) would be beneficial
  • Video discussing the topic here
  • See how location is important here
  • And how witnesses are important here

What is a POC Challenge?

  • This is used to confirm your proof of coverage, and where you are physically compared to other miners
  • See the docs here

Which mods should I invest in?

It is best to see how your miner performs first with what it came with - all manufacturers send overall good antennas.

Your priorities should be,

  • Elevation
  • Line of site to as much as possible should be your second aim, the less obstructions around the better
  • The antenna length should be kept as short as possible (use LMR400 to minimise loss please)
  • If all of the above is problematic, have a read about antenna placements here

What about Emrit IO / Hotspotshare?

Emrit has a application process where you provide your location and they will consider sending you a Helium miner for free. Emrit in turn will give you 20% of the earnings that the miner makes.

Assuming you are approved, this appears as a low-risk and little-investment opportunity to see how a Helium miner will perform at your location.

Some things to consider,

  • Power (~10W, ie. minimal) and broadband use is of course your outgoing costs
  • The miner is never yours, there are T&C’s to agree with
  • As you take no risk, you will only get 20% of the rewards
  • The device is not linked to your wallet


Do they ship to me?

If I have two miners do they challenge each other?

All miners send/receive challanges - see Vosk’s video here

I have a finance question

  • Good site for calculating any tax on your HNT mining at minertax.com
  • Setting up a profit-sharing business with miners? Have a look at hotspotty.net
  • Good chat about known risks here

MX2Pro vs Helium?

Still early days for both projects however here is one writeup.

You can use a M2 Pro and Helium miner within the same 300m without any concerns

What is HIP-15?

HIP-15 is the Beaconing Rewards system and covers how Proof of Coverage is rewarded.

What is HIP-17?

HIP17 covers the hex density award scaling for Proof of Coverage

What is HIP-19?

HIP19 is the process by which manufacturers apply to create Helium miners where they go through a certification process. This is documented by Helium here.

What is a lonewolf?

A hotspot/miner that can not see any other miners to validate. Vosk talks about it here.

Talk to me about validators

Lone wolves (no hotspots close by to validate) currently make on average 1.5 HNT/week - once validators go online later in 2021 miners will not validate so this compensation would go away.

Talk to me about how consensus works

See this

Am I too late to buy a miner?

  • Should I buy a miner? Vosk talks about it here
  • Understand ‘Miner Placement’
  • Research and do the math yourself

Can I make my own miner?

You could in 2020, you cannot anymore, if you create one it would not be signed by Helium and therefore you would never get rewards.

There is a roadmap for Light Hotspots to go in beta, read about it here

Can I put the miner in my car/truck?

No - the position needs to be asserted, see the below on the re-assert fee. Youtube link discussing this

I need to move my miner / remotely assert a miner

  • There is a ~$10 re-assert fee to assert a new position (distances more than 300 meters)
  • Vosk talks about the process here

Someone mentioned 5G?

This was announced 27 April 2021, have a read,

  • NOTE this is US only for now and completely optional
  • The idea is that it will provide 5G coverage for areas with bad cell service, therefore expect a lot of Internet use as such a site and expectations of low latency and high throughput

More reading:

Rant mode:

Just some opinions from someone who has been in the telco space decades ago.

I’m firmly under the opinion that the costs would be prohibitive for the typical ‘home user’. Why?

You will be providing cellular (voice & data) services on behalf of a provider who do not have coverage in the area by means of a roaming agreement with the relevant network providers the end-client is subscribed to.

This means that it automatically attracts several legal requirements, especially as any service which can carry emergency services traffic attracts SLA’s, ie. you cannot be in a situation where ‘911’ is called and the service does not work.

Typical requirements I’ve seen in the past include,

  • Multi-gigabit up&down-links (2x circuits for redundancy)
  • Multi-hour UPS backup
  • At least 2x of all radio equipment for quick replacement
  • Agreed upon SLA’s - with downtime penalties (in thousand dollar ranges) per hour

This leads me to the belief that the Helium ‘5G’ option is not for the typical home owner- but rather aimed at commercial entities.

That said - this is based off decades-old-experiences and things might have changed in that time - hopefully so for the better.

Can I contact a owner of a miner?

Not directly - however heliumhosts.com has been setup to add a element of connecting owners.

What if someone steals my miner?

Theft has little purpose as the miner has your wallet address on it - they would be mining to your address unless you released the miner beforehand.

How do I pitch one to a friend?

Want to put a miner at a friend/neighbour?

  • Discuss that the device does IoT
  • Discuss security, dog-trackers, etc will connect to it, not WiFi or your network
  • Discuss impact to the person - ie. little electricity use, not more than a couple of hours of Netflix use in bandwidth per month
  • Benefits - pay their internet? A %?
  • Video discussing this here

How much electricity does it use?

Assuming 0.15c/kWh (which is above average):

  • Bobcat says no more than 0.12kWh per day, so worst case: 56c per month
  • Nebra says rated up to 15W, so worst case: $1.67 per month
  • RAKv2 says powersupply up to 5V/3A = 15W, worst case: $1.67 per month
  • SP NA says 21W, worst case: $2.34 per month

Where can I exchange/trade HNT?

You can transfer/buy/sell Helium HNT at,

What's with the miner names?

They are randomly generated to make it fun but memorable, the Helium COO talks about it here

Activation rate

For those interested in how many units of each manufacturer are going online every day - I keep a tally here. Data is from Helium’s Makers hotspot explorer

Want to know where those new hotspots are? This is a useful site


I just bought a bobcat miner. Now I saw a medium article about FreedomFi & 5G…did I just purchase an outdated miner?

no, that 5G miner will be potentially 10x more expensive

Removed the mugglepay video as that guy is a competing affiliate now. He hit the classic bait and switch w/ his link lol


Bobcat Miner has updated their shipping estimates

Orders paid before 12 pm PDT on 5/1 will be 8-12 weeks. After that cutoff, it will be 12-20 weeks for delivery.

Thanks - updated

Going to nominate you for thread of the year on VoskCoinTalk, that needs to become a thing and custom forum badge lol


Anyone know If the bobcat miner frequency US915 works in Chile AU915? Cheers

Hello i’m new here. I understand the miners need to be at least 300 meters apart, but what is the farthest they reach? I have a miner coming, but the closest miner to witness is about 1.25 miles (2 km) away. Are they too far to reach?
