Hi everyone, for the past few days my Nano 3s keeps shutting down and restarting constantly. Could it be due to high CPU temperatures? Should I replace the thermal paste? How should I do that?

I wanted to mine and found this "looking legit" company millionminer

So i choose a miner that costed 6500 usdt and sent them my money

Scam part one . The product was not available . They falsely advertise products as available so that people will send them their money and they dont have the products.

Scam part two. I immediately asked for a refund and 14 days have passed and they have not sent me my money yet . Every day they find an excuse . The finance department is processing blah blah , we will send you your money in 24-48 hours blah blah , we are dealing with your problem blah blah

Usually legit companies send a refund within the same day as far as i have experienced .with them 14 days and no refund yet!!

Its just 2 clicks to send usdt back to someone and they cant ....

Hey everyone,

Has anyone here by any chance had any experience with Dahab Miners (Dahab Miners Electrical Contracting LLC) out of Abu Dhabi?  

I am considering buying a miner (Bitmain Antminer S21+ Hyd) through them and having it hosted locally.  

Did any of you run into issues in the past regarding delivery, setup, ongoing electricity costs, or support?

I'm hearing really good things about the new Bitmain BM1373 chip. you guys think anything new might be coming out soon for home mining that's at 40TH rate or more? thanks!

Does anyone know where I can either find an exhaust shroud for the a15 and its power supply or a 3d model that also can vent the heat from the power supply right now I’m only able to vent the heat from hashbords and it’s very frustrating because my temps slowly creeping up and causing problems for my other miners

New to crypto here, I just bought myself a bitaxe and I’m new to all of this so I was wondering if solo mining or a pool is better? I have school from 8-4 so I didn’t know if either would effect that

I have been doing some research into mining and I think solo is the way I am going to go as more of tech geek/enthusiast. From what I have read it seems you can either go solo/lottery, or you can join a pool and get paid way less but way more often. I understand running solo there is a pretty good chance my machine will only ever consume energy and never pay me. I'm ok with that.

My question comes down to, can you do a hybrid or solo mining and pool mining. Like, can I run my own pool comprised of my machine as well as pooling together machines from just friends and family. Then have this set up to combine hashrate and mine "solo" for better chances in the lotto? Is there any difference between doing it this way and having each machine set up at different locations running solo on it's own instead of in a pool?

I've recently come across HashNet and I'm trying to understand whether their mining model makes sense from a technical/economic perspective.

From what I understand, they provide access to ASIC mining/hashpower while handling the infrastructure, electricity and operation.

They advertise relatively high monthly returns, which obviously makes me skeptical. I'm particularly interested in whether the economics make sense after electricity, maintenance, difficulty increases and the 2028 halving.

Has anyone here actually looked into HashNet in detail or used their service.
If this post isn't appropriate for this subreddit or violates any of the rules, please feel free to remove it. I'm just trying to get some opinions from people with more mining experience than me.

One thing I've found interesting about the recent BIP-110 controversy is how much discussion it's sparked around miner influence and network governance.

Some people argue miners should simply follow economic consensus. Others think miners have a responsibility to influence the direction of the network through the chain they choose to support.

As a miner, has this whole situation changed how you think about your role in Bitcoin?

Do miners just secure the network, or do they have a bigger responsibility when contentious proposals come up?

Curious to hear thoughts from people actually running hashpower.

Looking for a portable miner. Price and power usage is not an issue.

noob question: I just changed my wifi ISP and so had to change it on the Nano 3S.

To do this I used the pin hole reset next to the USB port to reset the device (as per many YouTube videos tell me). I thought this was a full reset of the device?

I connect to the new WiFi network through the app and the device boots up and starts hashing. My understanding is a hash rate is only shown if the device is actually mining?

Since I reset the device, I would expect to have to reconfigure the mining pool? Or has it somehow remembered via the app? How do I check where the device is mining to? In the pool config tab, all 3 addresses are blank.

I am in California and have a very expensive mining computer hosted in a mining farm in Nevada since 2023. The initial contract was for two years with auto renewal, with a 90-day termination notice for either side. From the beginning, my miner was frequently offline or operating below the capacity, and the host informed me that it needed repairs. It went to repairs two times over two years and the second time it was replaced by the manufacturer under warranty. But the new miner started experiencing malfunctions at the same rate. In 2025, the host sent the miner to their own repair shop and told me they were providing their spare computer for me to continue the mining. So, I am paying the same rate and receiving the cryptocurrency at the same rate. It operates at a massive loss - I am paying the host more than what I earn. Once at their repair shop in late 2025, my miner remained there. I've been suspecting fraud - I think they've been disassembling hosted computers for expensive parts and potentially redirecting some of the mined currency to their own wallets. In July, I sent them a 90-day notice to terminate. Under the contract, they are required to return the miner to me. However, I have not heard back from them. They don't pick up the phone. I suspect that they no longer have my miner in their possession. What do I do?
