I suppose it's hard to CPU mine profitable if you're really dumb. You guys best stick to mining Ethereum or whatever if you need a step-by-step Youtube-guide to hold your hand...

Coins to check out:

*Magi (XMG)
*Verium (VRM)
*Credits (CRDS)
*Monero (XMR)
*Gridcoin (GRC)

I added Credits in the Cheddur app (used to track cryptos) but couldn't find all infoz, for example somewhere to get the current price of the coin. Would be nice if one of the devs could double-check the added info and perhaps supply the Cheddur team with complete info. I'd love to have the coin in the app to track price etc

Contact the app team here with corrections and additional info: https://www.cheddur.com/support/contact

And if you use the Cheddur app, give CRDS a rating and add your wallet adress

Dump the battery and run with charger, set a fan up to cool your phones, dump 20-30 of them in an mineral oil tank to cool them, take the plastic shell off to help with cooling etc etc. Like I said "if you know what you're doing".

Cool link! But I doubt it'd be profitable considering the amount of pencils and paper you would use  

On topic: Check out some CPU-only coins. You wont need to buy any new hardware to mine those and laptops are quite power efficient.

Both those links concern malware. No problem running a miner on a phone if you know what you're doing.

Only in-wallet mining so far.

Merry Christmas!

Difficulty is changing a lot, from 0,3 to 0,002 in 30 mins

Hmm, you should've hit at least one block in all that time. Lots of us Verium miners use SBC rigs and I've never heard anything about higher h/m machines being more suited for the job. Have you joined the Slack? https://vericoinandverium.slack.com/messages

Thanks!

I don't want to advertise other coins in the Magi thread but if you look around a bit there are at least 2 more good CPU-only coins And then of course, lots of crap ones. But I really do recommend the XU4s for mining. I'm sure you can get hashrate higher than 24khash/s, but I haven't bothered tweaking the settings for XMG mining.
Odroid, the manufacturer of XU4s also released a SBC called HC-1 which is a bit cheaper than the XU4 and is better suited for mining. Have a look here: https://bitcointalk.org/index.php?topic=2254852.0

I've been trying to mine XMG with XU4s. They give me about 24khash/s each, running at ~11W. I suppose that's pretty good but atm I got them working at mining some other CPU coin.

i tri mine wit my gamur pc gpu. mine bitcoin. no work. dis meen gpu mining no work

1. Open wallet.
2. Go to debug console.
3. Type <setgenerate true X> where X is your desired number of threads.
4. <getmininginfo> outputs your hashrate etc.
5. Read the fucking topic, "CPU-only mining".

Hi, I'd suggest reading Birtys guide here: https://steemit.com/verium/@birty/cpu-mining-is-back-a-complete-how-to-guide-and-profit-analysis-for-verium-mining-on-a-farm-of-single-board-computers-part-1

It's somewhat outdated but still a nice starting point. Also, join the slack for Verium and Vericoin. Verium is a great coin to CPU mine and lots of people are running interesting CPU rig projects: https://vericoinandverium.slack.com/

I'm by no means a pro hax0r but I like having projects to mess around with in my spare time. Lots of people out there are more knowledgeable than me but if you have any questions I can try to respond
Odroid XU4s are great SBCs to get started, but make sure to also have a look at the Odroid HC1 (which is essentially a stripped down XU4 with a big heatsink) that jacko, OP of this thread, is using. The main point of my mining rig was not to make a profitable machine, but to have fun building. I'll make a profit eventually, but custom machined front plate etc etc will give me a loooong ROI.

Lots of cool CPU only coin out there, and for example Monero can still be profitable even though it's GPU mineable.

And as I told you at Slack, I love Sally 

@sundownz damn that is some serious CPU powah!

Here are some pics of my newly finished XU4 rig. Some descriptions at imgur:

Hashing at ~450h/m each for a total of 5400h/m and mining Verium of course :>

What parts of your OS is not GPL/open source?

You can surely mine Verium profitable with your CPU. I'd suggest mining in a pool with that hashrate. Check this pool out: https://vrm.poolinat0r.com/

Also be sure to join the Verium/Vericoin Slack which is where most of the action takes place and where you can ask questions. I'm sure you can get your hashrate up by tweaking your miner and OS.

I'm mining with my XU4s sometimes. Getting 24 khash/s stable. I'm sure I could get it somewhat higher by tweaking but haven't bothered.

If you want to solomine check this: http://resources.vericoin.info/wp-content/uploads/Verium-Solo-Mining-Guide.pdf

If you prefer pool mining you can follow these instructions:

The coin went down today yes, but if you look at a chart showing more than 24 hours you'll see what's going on: https://www.coingecko.com/en/price_charts/veriumreserve/eur#panel
There was a big pump and then the price went down to "normal" levels. If you look at the graph since launch the value is rising. Cryptos fluctuate a lot. It's normal and what makes this interesting.
