To answer one of your questions:     https://www.akminer.com/, https://www.419mining.com/ or https://www.parallelminer.com/
I've bought from 419 & parallel in the past. Ak just come recommended by others but I have never used. There is also aliexpress but there is obvious risks there.

yeah, some coins have their own port for nicehash if you click on them.

You have no leverage. Again if you get the host taken away, then the operator has no reason to go back up and payout any miners. You basically will be giving them a reason to exit. Not your keys, not your coins. Sadly in mining the operator has all the leverage. Also being incorporated in Russia gives most of the miners little legal recourse right now.

If you are so pissed off, Hire a lawyer. Or wait until you finally get a payout. Those are the only option you have that make any sense. And yes the pool has another option of closing its doors and taken all our crypto, which it has not done yet. You should not force this last option, which is all you would be doing. I never said the situation does not suck. I do have Eth stuck on the pool too. I'm just say the pool works for other coins again, if you have some patients we might eventually get our Eth out. A better chance than if you ruin the pool's hosting.

As to the ownership, you might be right, however, moving the corporation and changing the name does not necessarily mean the original owner/operator is not still there. Might have had to change the name to incorporate in Russia. Here I can understand your reasoning.

I'm just saying it's a pretty douche thing to do, when pay outs for a lot of the other coins have started working again. I could not exchange or withdraw any ZCL for 3 or 4 months (I usually exchange it for ETH) but was able to withdraw before the wallet gets removed (the wallet was eventually fixed). You should know that your emails in Russian are a waste of time, MPH does not speak it, the pool has only ever had forums in English or Korean which would imply the languages they speak(don't need to be Russian to use a Russian hosting service). And I've been mining here on and off since 2016 if you think that matters. It is why you should always research the pools you mine at, a lot of the coins are working fine now with payouts, so MPH has not actually been inactive.

It's not like anyone else right now could fall into your so called trap since the auto exchange function is off and ETH is no longer minable. Personally I would would rather wait a year to get my ETH than some @sshat ruin the opportunity for that to ever happen.

You do know that if you do what you propose you are definitely never getting your Eth or other coins.  This pool has been around for many years and has had problems off and on during many periods with different coins. Most of the pools history it was run by one man, who also worked a full time job, I think he has some help now but probably not enough. Patients was always needed and every issue has always been solved. Not to say that these current problems have been taken a long time to fix but it looks like the pool had/has issues with almost every coin.

Dingo is merged mined, so you never really mine it directly. Basically you mine another coin that shares its hashrate with Dingo (and other coins too).

The ttyUSBx number does not match the bus device ID. Navigate to the dev folder and search for ttyUSB*. You could just try ttyUSB0 and so on ttyUSB3... usually moolanders show up as the first usb devices and newpacs do not show up there at all. If you have been trying to hotplug them the number could change.

You have to point cgminer and bfgminer to the miners using --usb and -S. I would also suggest starting the Gekkoscience stuff first.

No, only Scrypt. Yescrypt is a different algorithm.

The original Apollo mined Scrypt, so you could mine DOGE; but the new Apollo BTC does not.

Doge's algorithm is Scrypt. Apollo BTC's mine Sha256.

An unbiased review?: https://youtu.be/_ik3blM5qw0

I'm just guessing but the decrease is part of the answer it also looks like the pool has an increased hash rate. It could be smaller miners that do not show up on the list (there are more than 15 miners). The pool has produced 3 blocks in the last 24 hours when it was only averaging about 1.2 a day, either the pool has gotten very lucky or the hash rate has increased.

Also a network issue could have developed between you and the pool raising latency that could reduce the hash rate the pool receives (this is unlikely but possible). Not everything is nefarious just because your payouts are not the same.

Sunday 23rd May 2020.#Dash block reward decreases by 7.14% every 383 days. Wednesday 10th April 2019 was the previous decrease.

I had the same problem.  Use the bootstrap, that fixed it for me.

That's an actually legit reseller.  I do not know if Jstefanop actually endorses him or not. Eyeboot has an actual website, that is is just his ebay listing. You can find to owner of the store around forum too.

I think you have to use the port if you only want to mine ETH otherwise the switch port will mine what is most profitable even with the default job set, it just checks the default first or mines there if there is a stratum error with profitability checking (if the pool can not tell what is better to mine).

There should not actually be a difference between Hot/Cold staking.  I think the difficulty is a bit up from the old wallet. I do not even get the same amount a day that I had.

Have you run any updates on the Pi?
You might want to delete bfgminer and rebuild.  From some minor research it looks like segmentation faults are often from build issues, though sometimes it is from missing dependencies on the OS. So I would try an update and reboot first and if that fails start from scratch. If you used the download from Futurebit I might redownload and unzip it to a different location.

Otherwise I have no clue...

What about people who are not serviced by Tokens.net because of where we live?
