It's not unusual actually, can't say for nerd but Antminers I got were also like that in the past, they had pools on them I am guessing as part of quality check.

 This a common occurrence or just something you noticed now? Likely not something to be worried about but can check to see hardware errors and  any other reported issue in your log. The S21 series have had their little run of issues, and finally is firmware is latest?

 If this is the first time you noticed give them both a reboot and see if you get the same results.

 I used both miningrentals and nicehash. Now not really using nicehash due to the amount of KYC and even having to verify the wallet you send from. I am concerned it may cause issue so avoiding that hassle.

 However, you can concentrate a lot of hash in one go on there as the rent is for actual hash power and not a rig. You set the price your willing to pay and how much speed. If your bid is high enough you can go nuts, if your bid is competitive it may come, give some, and if a new higher big comes in they will shift over to there. Obviously if too low you could be idle for an awful long time!

 Miningrentals you rent rigs for set periods, but can swap them around to different mining pools if you so choose. Many you can extend the rental period, the owners usually set the minimum time to maximum you can rent it for.


 Take a look over both and understand how they work, roll the way you feel comfortable.

 Just to also help with understanding, luck is just based on your hashing power vs the network entire hashing power. It's a big lottery and every hash is one entry with a winner about every 10 minutes, after that everyone hashing is back at it! However even at 60TH you will end up a winner sooner or later. Provided network hash rate remains the exact same (which it won't) you will find a block between the next 10 minutes to about 315 years, statistically.

 The most difficult share mined up by the pool has nothing to do with luck calculations or when the next block is about to be found. Best shares by the pool could even be floating in the millions then all of a sudden block is found. All luck means is the average time it should take based on hash rate being deployed vs difficulty.

 Your hash rate determines how many guesses your miner spits out per second, you just need 1 hash in order to submit. The difficulty of 121.5 Trillion only means how hard it is for the miners to guess right, but that's based off total hash rate from everyone. Your hash rate is just how many guesses you are submitting per second.

 I would always advise getting a ledger to store anything or another hardware wallet and make sure you back up your seed phrase in a very safe place. Don't ever mine to places like an exchange, they can get hacked, go bankrupt, change things or even just close down on you. Not your keys not your crypto!

 That's not what I meant, and you're right. They do snag a portion of your hash but in turn *if* you mine on their pool it is reimbursed in the form of bonus.

 What I meant to clarify is it sounded like this diversion affects your odds of mining up a solo block, this in itself is not true. It also makes it per ASIC and how you plan to deploy it, for example an older S9 does have a low power mode already but you can further decrease it with an after market o/s like braiins. You can also crank it up to hash out a lot more, I was just clarifying my case where I mined on several pools without issue and yes gave up some hash for it, so comes to user and their goals.

 For me I managed to I average below 21w per TH, stock would do about 28w per. So I am saving about 25% power costs and all together (without bonus if I would mine on braiins) dropped 20% in hashing. So for me, it makes the gain greater than the fee.

 I don't think this is how braiins works, I have it running on a few of my S19 types, where I split the pools to mine on. For example I direct a small amount of hash to solo mine while the rest is one a pool like braiins. You can mine on several pools with that o/s simultaneously without issue, and the 2% fee is basically an invisible pool the miner points to.

 I ran several pools (think it was 5 pools all being mined on the same ASIC), and even solo mining other coins like BCH - it had actually found blocks. I see the 2% loss in hashrate to make it more efficient and then can allocate a small portion to solo worth while. I have found no indication in loss of mining, in fact I view being able to make the miner more efficient worthwhile, and if mining on braiins with their o/s also gives an equal bonus by no pool fee so evens out.

 What I am now trying to test is if the "main pool" somehow is better to solo mine than say "pool 2" or whatever down the list.

 Sounds like hardware issue, if it offers a log try reviewing it for the error if you can't visually notice anything. If you mean higher difficulty port it will not increase your chances of finding a block, the pool should adjust difficulty automatically for the miner.

 I also using Braiins and seems to be alright, this allows you do redirect some hashrate for solo.

 Higher performance for difficulty is fine, an S19 or above can do it but if you just have a single rig for part time then stick to 3333. Point of high difficulty is for big rigs of multiple miners that would otherwise take up pool resources, in the end is doesn't make any difference towards you solving a block.

 For the addition you can still use your same personal wallet address (never mine to an exchange) and just give them a name if you like to see how each is doing. Otherwise to the same wallet, it doesn't make a difference if you use the same wallet or use a new one for your second ASIC. Odds will remain the same whichever way you roll. It's a big raffle and every ASIC that is able to contribute 1 hash can be drawn!

 Congratulations on the solve! Looks like 3Ea12CGa2T1xRchP4zyng684CcqbicFUeJ still has some rental time remaining as current is still right around 82PH.

 Congrats to 36AisvWi1UiwLTeTZxLzindAkorqeUc3tT!

 May have been some heavy rented hash for a few hours noticing the pool luck was getting close to 100%, or figured lightning will not strike twice so move the rented hash elsewhere. Does look like it was being monitored by the miner.

 You take different routes to different sites / pools or anything on the internet through various DHCP servers. There's always somewhere on the internet that you will not be able to connect to but will sooner or later. Next time try a full restart of your internet.

 I believe he's now just spamming to advert donations for his alleged shit coin.

 Very nice of you for some hobby farmers, I would even take you up on it. Just be careful shipping those S17s! Fragile as can be, heat syncs often fall off the boards.

Look for a simple "Bitaxe" miner or with cheap power "Avalon Nano 3" and you will be good to go for lottery solo mining.

 I actually have an S9 dedicated for solo, and consider that a lottery play.

 I see where you're coming from, and it really is encouraging to all those solo miners out there running barely 1T against those mega farms where a single ASIC is hashing at 100T+.

 Wouldn't say amazing performance, it was performing as designed. Amazing luck though!

 Once within every 3,500 years... so can be in 10 minutes or in 3,500 years. With current stats for hash & difficulty of course.
