Gm Nostr! Up and at’ em this morning. Have really been considering a home miner. Would yall have any recommendations? Also, is it worth going with something smaller like a bit axe or the Canaan Avalon nano 3s. Or should I just go for an S9? Not much difference in price between the 3.
Thanks for the help! #asknostr #bitcoin
I have both a Bitaxe and an S9, so I can give you some insight here.
If you plan to use the heat generated by the S9, go that direction. If not, go with the Bitaxe. Yes, they are about the same price up-front, but the S9 is going to use WAY more power per TH than the Bitaxe. Efficiency is important, and it's why the Bitaxe doesn't cost 1/10 of the price of the S9, despite producing less than 1/10 of the hashrate.
An S9 can get you 13.5-14 TH of raw hashing power, but it's efficiency is only 0.1 joules per gigahash. Compare that to a Bitaxe Gamma, which is only about 1.2 TH, but does so at an efficiency of merely 0.01 joules per gigahash.
Then you have sound pollution to take into account when talking about home mining. The default fans on the S9 are LOUD. You will need to do something to mitigate that if you want to live peaceably with anyone else in your household. Even if you replace them with quieter fans, though, it's still pretty noticeably loud when running at full power. Most folks using S9s as space heaters are running them at half power, and they are not bad volume there, but then you are getting even worse efficiency and less overall hashrate.
Also, keep in mind that you probably aren't going to be profitable, even with a Bitaxe, unless you have really cheap power. Consider it a hobby and something you are doing to learn more about how Bitcoin works, and get some KYC sats at a bit of a premium cost. Of course, you might also go the lottery mining route, where you don't make any sats at all unless you are fortunate enough to find a block. That is always an option, too.
Thank you so much for this detailed response! I’m leaning toward pool mining. I don’t plan on making a profit, just more for a hobby, knowing full well I’ll have to pay a bit more for the kyc free sats. Do you like one miner over the other? Does the S9 have any software options that make it easy to underclock/run at full power like the Avalon miner does? I think it’s just braains os, but am unsure.
I flashed Braiins OS onto it. Depending where you get it from, someone else might have already done that. Very easy to underclock with that UI.
Bitaxe has its own firmware and dashboard UI, but is also very easy to manage.
If pool-mining with either a S9 or Bitaxe, you'll want to go with a pool that has lightningpayouts. If you are just doing it as a hobby and you also run your own Bitcoin node,I can't speak highly enough of using nostr:nprofile1qqsq9k04vahllseell55m74n3047y88pzlr0z5yany32st29fapqmgsppemhxue69uhkummn9ekx7mp0qy2hwumn8ghj7un9d3shjtnyv9kh2uewd9hj7qgawaehxw309ahx7um5wghxy6t5vdhkjmn9wgh8xmmrd9skctc87ckyu pool for lightning payouts with DATUM on your node so you are making your own block templates.
