Antminer S3 is a popular machine. Should do a lot better than U-series devices.

Vircurex isn't on the list. Did you mean a different one?

Putting addnodes in your bitcoind configuration is not how you set up a pool with multiple servers. That will just connect your bitcoind nodes the same way all bitcoind nodes in the world are connected.

The correct way to set up a multi-server pool depends on your pool software. Check the documentation or talk to the people who made it.

Thanks, I will have a look at the exchange links. Indeed it looks like some changes are needed.

What is the problem with Camp BX? Except for low activity?

Website operational. Live hashrates are coming back now.

Website issues right now. Working on it. Mining functioning as normal.

It could be related to your low hashrate. A difficulty of 4 might be good for you. But Bitminter now doesn't support difficulties below 64. This is because some modern ASIC machines cannot handle low difficulty.

It's probably causing you to only send in work once every 1-2 minutes. Some home routers will cut connections if they are idle for as little as 30 seconds.

I suppose it could be something else, but that is one guess.

500 GH/s currently gives you 0.07367716 BTC per month, which is currently worth $33.08. This changes when the difficulty and bitcoin price changes.

To be profitable you need to buy the machine(s) at a good price per GH/s and you need electricity at a good price.

Many beginners think you earn a lot of money if you have a lot of hashpower and you lose money with a small amount of hashpower. That's not how it works. More hashpower will speed things up. Sure if you are profitable you earn money faster. But if you pay too much for electricity or per GH/s then getting more hashpower just means that you lose money faster.

The quick updates on the livestats are extrapolations based on your hashrate. There is an adjustment from the server once per minute.

If you send in one proof of work at difficulty 256 then your proof of work counter on the server will go up by 256. And that happened in a single work submit.

Since the server updates your data approx. once per minute you could look at the workers page where there is no extrapolation, wait one minute, click the little refresh button there, and see how much the accepted count goes up. It will be some multiple of the worker difficulty you are on currently. But you wouldn't be able to tell two work submits at diff 256 apart from a single one at diff 512.

Try having a look at cgminer when you are able - much easier.

Do you mean it is stuck at exactly 256 all the time?

Bitminter worker difficulties are powers of 2, with a current minimum of 64. So 64, 128, 256, 512, 1024, and so on. If you don't set a minimum then you will be started on 512 currently.

The mining server will adjust up your difficulty if it makes sense for your hashrate. The aim is to see roughly 20 work results per minute from your worker. You can change this number in the worker settings. You can also set a difficulty minimum which is mostly useful to make the initial difficulty ramp-up faster when you connect to the mining server to start mining.

Note that from you change difficulty settings on the website until you see it active on your workers can take up to 20 minutes (worst case).

Mostly you shouldn't need to set minimum difficulty or the work results per minute target. The mining server will start you at 512 and adjust your difficulty as necessary when it sees how fast you are mining.

Yes, you need ASICs to mine. Mining on a graphics card takes several million years to mine one coin.

There are two types of cheap ASIC devices.

Cheap per device: These often cost only 10 USD. But they only do 1 or 2 GH/s which means that they are extremely expensive per GH/s. You would be lucky to earn back 10% of the price of the device.

Cheap per GH/s: These are more expensive devices. But they are cheap per GH/s and can make a profit. Have a look at Antminer S7 plus power supply at bitmaintech.com - that's not a cheap machine but you can calculate the price per GH/s and use it as a base for comparison. Have a look at ebay and similar places for older Antminer S-models, kncminer, spondoolies, etc. Compare to the GH/s price of the S7. If a machine doesn't come with a power supply then always factor that into the GH/s price.

That's odd. But at least it works now.

Oh and.. a big thanks to magus777 for being our savior today!

It's on my list!


Thanks for letting me know.


Is it otherwise working and getting work accepted?

Could you try us2.bitminter.com:3333 and/or eu1.bitminter.com:3333 and see if those are more stable for you?

Awesome I have been answering the same questions for years, so I'm getting good at it


This is highly unlikely. PPS is extremely dangerous for a pool. It only takes a little bad luck and the pool is bankrupt. Most PPS pools already either went bankrupt or stopped offering PPS.


Peercoin does not support merged mining, so this is not possible.


This would be a possibility. My impression is that most people are just annoyed by the namecoins and want them removed. Autoselling might be one option.

It's not true.

Huntercoin doesn't seem to make much sense to me. And namecoin can be bad enough. There's problems with the namecoin software. People complain that they want to mine bitcoin, not namecoin. Etc. etc. I sometimes wonder if having Namecoin is positive or negative for the pool. Yes, you earn a little more, but there are so many misunderstandings and technical issues. Not to mention every web wallet I have seen for namecoins are scams.


Your work is registered in shifts and doesn't disappear no matter what you do. When a block is found the work in the last 10 completed shifts gets paid.

There is no "ramp up" in PPLNS. This is a confusing point of view that makes people misunderstand the way it works. See it from the point of view of the work in the shifts, not the blocks. If you just look at the blocks and how much you got for each one then you will only confuse yourself.

There's often one easy and one difficult way to look at the same thing. In our solar system the movements of the planets are easy to understand from the point of view of the sun. It's harder from the point of view of the Earth.


You get paid when blocks are found. Average time to find a block for us is around 41 hours now. Difficulty went up a lot lately. That's the average though - bitcoin mining is a bit like a lottery.


Depends on how much of the work in the latest (when we find the block) 10 shifts was done by you. If you have 1% of the pool hashrate, then you get 1% of the block income.

There is some info on payouts here: https://bitcointalk.org/index.php?topic=27062.msg2769824#msg2769824


It's bad luck. Average time to find a block 41 hours. Now we're at 144 hours. It happens. But luckily it can't rain every day.

I had another crack at the live stats audio bug that would sometimes play a casino sound even when there was no new block. Clear the cache in your browser to ensure you have the latest live stats version and this problem should be gone the next time you reload the page.

Please let me know if you still hear winning sounds without winning

You can also get a notification on your mobile device by installing the Yo app ( https://www.justyo.co/ ) and sending a yo to BITMINTED. Granted, a "yo" is not as cool as a crazy casino sound, but otherwise it works very well.

You're welcome - happy to hear you like it

This is exceptional bad luck. Hopefully it will be a long time until we see something this unlucky again.

For those who are worried about high variance but also don't want to contribute to the situation we have now with China controlling 65% of the global hashpower, mining in multiple smaller pools (like you are doing, Darthswan), can be a solution.


Yes, something like this has been suggested before. I have average hashrate numbers for shifts, but currently nothing more fine-grained than that. Not sure if I should make graphs out of those or start collecting some more fine-grained hashrate data.

Veldig bra. Takk for at du påtok deg dette, Sturle.
