I did four hours of research after I wasn't able to connect 20 USB ASICminers to two $7 USB hubs from eBay. Be advised: you need to get expensive hubs that advertise their amperage as half the number of ASICs you want to use; ASICminers use a LOT of power. The cheapest I found were Amazon brand (yes brand) at $20 for seven ports, plus tax. The price of functional hubs has gone up with increased demand brought on by the ASIC market. submitted by
Edit: There was prior work
I didn't know about from a month ago!
Hi, this is a summary of my findings on 0xMonero, which claims to be "a mineable privacy focused project".
The contract was deployed on April 18th
of this year, verified on Etherscan
the same day, announced on Twitter
soon after. It was announced on Bitcoin Talk
about ten days later. 0xMonero's contract is an uncredited rip of 0xBitcoin's with only very small changes
. The mining software recommended by 0xMonero
was written for 0xBitcoin. There are two other
more modern miners written for 0xBitcoin, but up until recently, they have only supported pool mining, not solo. My suspicion for why 0xMonero recommends the older miner is that they don't have anyone competent to run a mining pool.
Here's 0xMonero's stats page
, and here's 0xBitcoin's
. Look familiar? 0x1d00ffff wrote that page for 0xBitcoin about a month after the 0xBitcoin project started in February 2018. Here's the initial commit
, and here are the changes 0xMonero made
. When 0xMonero ripped it, at least they left the author's Etherscan link
at the bottom.
Here's 0xMonero's official GitHub
. As of now, there are 20 repos, but they are all forks, zero original repos. I've been told that 0xMonero has ten developers. When I asked to see their GitHub accounts
, I was told that they were all too concerned with privacy. That doesn't make sense to me, since I've been doing anonymous development under various identities for years. Here's the account associated with my work for 0xBitcoin
, and here's another project I work on with other anonymous developers
Why does 0xMonero make reference to Monero? I don't know. As far as I can tell, 0xMonero has nothing to do with Monero. I can say with certainty that since 0xMonero's contract is an almost identical copy of 0xBitcoin's, and 0xBitcoin deliberately did not include privacy features, there are no privacy features in the 0xMonero contract. They would have to be elsewhere. But as far as I know, there is no other code to look at.
Here's a piece-by-piece analysis of the claims on 0xMonero's site
Here's a thread
- "Mineable + Private" It's mineable because it's a copy of 0xBitcoin. It is not private.
- "Works with all Ethereum wallets and DEXs" True, it is an ERC20.
- "Built on the Ethereum blockchain" True!
- "Only 18.4 million tokens can be mined" True. This is one of the few modifications 0xMonero made to 0xBitcoin's contract.
- "zk-SNARKs and 0xMixer" zk-SNARKs is a thing, but I don't know what it has to do with 0xMonero. I cannot find any indication that 0xMixer exists in any form.
- "Scalable to 10,000tps" Nonsense, as far as I can tell. It'll be able to do whatever Ethereum is able to do.
- "Mining" They instruct how to run mining software that was written for 0xBitcoin, as explained above.
- "View Mining Statistics" This is a rip of a statistics page written for 0xBitcoin, as explained above.
- "Exchanges" True! 0xMonero is on some exchanges.
- "Wallets" True! 0xMonero is an ERC20, so it works with Ethereum wallets.
- "Chainhop is an interoperability solution utilizing token bridges to other blockchains" I can't find any original 0xMonero code related to this. They link to Incognito, which is a separate project that AFAIK works with all ERC20s. They mention zk-SNARKs again, but it's not clear what it has to do with 0xMonero.
- "0xMixer" I can't find any code. I couldn't find any the last time I was looking a month ago, either.
- "0xLock" USB device of questionable utility developed by somebody else. Is it like a Ledger? I don't know.
- "0xDEX" Not operational, no code can be found.
- "Casino" From what I understand, some third party offers to sell gambling setups to Ethereum projects. I think it might be the case that anybody can buy this and have it set up for them in a few hours.

who claims to be a top holder of 0xMonero. In that thread, I asked many direct questions, and was not able to receive any clarification or substantiation of any aspect of what 0xMonero says they are working on.
When I couldn't get answers in that thread, I reached out
twice to the official 0xMonero Twitter account asking them to start a thread where it would be possible to get answers. I got blocked
. At the same time, I was blocked by another related Twitter account. Here's that account lying about 0xMonero's (nonexistent) privacy features
I started talking about this stuff on 0xMonero's Bitcoin Talk thread
about a week ago. I have been unable to get any answers there, either. But someone in that thread reported me. For what, I don't know.
I think that's it for what I know about 0xMonero at the moment. Please let me know what you think. Thanks.
Edit: Here's that related Twitter account lying about 0xMonero's nonexistent privacy features again
Edit: lying about 0xMonero's nonexistent privacy features again
, and AGAIN
. Suggesting to people that 0xMonero is somehow private is dangerous.
Edit: ... lying about privacy again
Edit: agreement about 0xMonero most likely being a complete scam from a second source: https://twitter.com/CryptoScamCases/status/1292753105097031680

Specs listed at the bottom before you pull your hair out and throw your chair out the window.
So for the past 2 months I have been digging all over the internet and troubleshooting this problem in every way I can conceive and I have been through quite the journey to get where I am now, only to find that I may literally be the only one suffering from my unique problem. I am going to be somewhat detailed so that anyone else suffering from this might find this post and learn something (if we find a solution).
I will try to keep it concise, but I need you all to know what I have and have not tried so that we don't waste everyone's time.
I have an audio buzz. This buzz comes primarily from analogue ins/outs on my PC's hardware. USB audio ins/outs have this as well, but not nearly as bad. I have a USB mixer that I thought was the culprit, because as I was setting up the audio system for streaming it became apparent. I initially discovered ground loops and tried to mitigate the problem by eliminating that. No dice. I systematically eliminated every single ground from the system and removed components to no avail.
It would literally be impossible for me to have a ground loop with my current setup - I really dialed that in before I moved inside the PC. Yes I have even plugged the entire system (AS A TEMPORARY - LITERALLY 30 SECOND TEST) into the outlet with no ground prong (bring on the hate) to eliminate that possibility.
The main problem that I have is due to the fact that I have to monitor "listen to this device" one input or another with the way my audio works. I need on the fly control of multiple audio streams at my mixer, so I have audio running from windows into my mixer and back out at 2 points. If I want to hear anything from one of them I MUST monitor it within windows. Monitoring the USB audio source does make things significantly more quiet than monitoring the analogue line in, so I am setup this way and things are better than they could be - but still not nearly acceptable.
Spoiler: it is due to coil whine which apparently to every single other person in the world is literally a zero issue because they can hide their PC below their desk, keep the culprit component enclosed in the case or use good headphones and not have to listen to the "hardware coil whine." Nobody hears their coil whine through their audio output. If they do - they've been searching for solutions to:
- Windows audio buzz/buzzing
- Realtek audio buzz
- HD Audio Buzz
- Buzz through headphones
- Buzz through speakers
- Microphone buzzing
- Etc, you get the idea.
These people that are searching this DO get the help they need. They simply disable a culprit unused audio source, disable monitoring "listen to this device" on an audio source, or reduce microphone boost or lower input/output levels. Some even have success disabling or enabling drivers (but I think this is not the ACTUAL solution - I notice that when I disable, uninstall or update devices/drivers, settings roll back too and any device I was monitoring is no longer monitored (or is monitored by the wrong audio output). My theory is that drivers have nothing to do with this problem - any apparent fix or genesis of the problem due to Windows Update or Drivers are actually just settings being defaulted or change by the audio system resetting.
I have also tried USB isolation and dedicated sound cards (which just pass the problem along). The problem is exactly the same no matter what because again - this is due to coil whine and it is at the hardware level at its core.
I discovered that it was coil whine after thinking I had discovered it was not coil whine. After all - removing my GPU from the equation didn't stop the sound from persisting in my headphones and a CPU can't coil whine (I don't think)... Anyways, I happen to think I have found a workaround last night. Yeah, sure - the buzz is still there but I am pretty sure it is not coming into my stream. Wrong. I load up a game (and I have my case side panel off) and before I can get into my headphones to check if the noise is back I notice it coming from inside my PC's case.
Quick throw-on of the headphones and a quick diagnostic tells me that indeed I am hearing the same noise inside the case and through my headphones. As mentioned before - the USB monitoring has lessened the problem, but not eliminated it.
So I have a big "HELL YEAH" moment. The problem is still there - but I know it is SOMEWHERE in this chunk of hardware I am looking at in front of me, and I can assume it is either the PSU, the Motherboard or the GPU.
So I take to doing some testing. In my months of research I found that when the computer is "drawing" as in pixels are generating new information, the problem is worse. I also know that loading my CPU to 100% significantly reduces the noise it is making and again I know these things can be related to changes in voltage at the CPU/GPU.
So I get a game loaded and go to work. Unplug Display Port - nothing changes significantly, but there is a small change nonetheless. But the monitor literally isn't drawing anything. The CPU is still relaying information (mouse position, the Game, etc). So either way the GPU is still receiving information, just not passing it on to the monitor.
Pull the 8 pin off the GPU - Fan cranks to 650% and I couldn't hear anything if I tried. So no dice there but I remember trying this before and not noticing much of a change either.
So now I open performance monitor, a web page with plenty of white on it (seems to generate the most noise) and start scrolling around. I notice that I get spikes on the GPU AND THE CPU when scrolling, and the noise in the headphones and at the hardware level is consistent with the movement and the readouts in Performance Monitor.
I run Cinebench r20, the CPU shuts the F**k up for the most part, but mostly because it is a high frequency now and most of it is out of normal hearing range (I have a wider hearing range due to ear training) and can pick up the low end of it (18-19khz) and think that if only this was all I had to deal with that would be great.
However, I am still getting quick spikes (during r20 test) when I move the mouse to highlight different tables on the performance monitor - so the GPU is also in on it.
Speaking of trying to isolate hardware problems: I have tried isolating the noise in the case using a straw and a notebook to block the sound and really can't determine if it is GPU, CPU, or some component on the motherboard or all three - I know it is not coming from the PSU because that is easy enough to isolate in my case (pun not intended - but enjoyed).
However, just because the PSU does not whine doesn't mean it isn't the culprit - if it is delivering unstable power to a component then it sure could be (correct me if I am wrong).
So here I am - wondering if you all have any valuable input. Please consider that I have read (no exaggeration) 200+ unique pages on this topic (broad as it was in the beginning) and I have tried everything suggested BESIDES replacing CPU, replacing, GPU, replacing MOBO, replacing PSU.
And that is why I am here asking for your advice. I need to probably replace components and I have to start somewhere - I cannot RMA anything besides the GPU (lost all proofs of purchase - paid cash for some items at retailers and lost paperwork when moving). And MSI will not RMA motherboards for Coil Whine anyway (according to numerous posts). I am prepared to buy a new MOBO and PSU, but I wonder where you think I should start.
Nvidia is looking into RMA'ing the card for me but they're hesitant.
I just want to list some other random things I have tried with no success so that you don't waste your time having to ask.
- Unpluged from motherboard
- USB leads
- Fan leads
- Audio leads
- Front panel leads
- (virtually, in BIOS) Realtek device
- SATA cables
- Powered USB hub
- Eliminate all grounds (outside of case)
- Reinstall windows
- Uninstall, disable, install Realtek Network drivers/audio drivers
- Disable fast boot
- Check for Bitcoin farming malware
- Isolate USB mixer
- Change power connectors for GPU
- Unplug all USB devices
- Unplug Network cable
- Everything main power related (grounding, loops, power conditioning, etc.)
- Modified power plan settings
- Disable C-states in BIOS
- Reset BIOS
- Remove all overclocks (GPU/CPU/RAM)
- Test with different speakers/headphones/combinations of onboard, sound card, audio ins/outs.
- Might as well have tested a USB/external sound card considering my mixer is USB and the USB audio out still has a problem (when being monitored)
- Cleared cache/reinstalled NUMEROUS programs
- Adjusted monitoring levels (this definitely lessens the buzz but it just comes out again when I increase the gain on a later part of the audio chain to make up for the loss in useful audio signal)
- Moving case/attempting to ground it and the motherboard better
- Removed/reinstalled PSU
- Shuffled wires/cables around to keep things out of contact or from running parallel to each other
- Balanced cables
- Tried all USB ports and front/rear analogue ports
- Probably several other things - I am getting very exhausted working on this all the time.
- Limiting frame rate in Nvidia Control Panel and Profile Inspector
Please let me know if you have any input or are suffering the same problem. I would really appreciate it and hopefully someone suffering a problem can find this post and learn something about their own situation from all the processing I have done.
