Good luck Belligerent Fool
Hello all using this thread. This is my first post on a bitcoin forum plus, I am also new to Bitcoin. I have educated myself as best I can given that the info is so distributed around the net as it is and, I have been mining in Slush pool for a month. I have read some of this thread but it is 441pages long so apologies in advance for asking stupid stuff.
I have two Bifury x2 with active cooling that run at 4.2Gh/s each, and one AntMiner U3 giving 60Gh/s and powered by an old Fujitsu ATX, all running on an old Dell Inspiron 6000, laptop 1.7GHz processor / 2G RAM / Win7 with two instances of cgminer-4.9.2. (one instance for the two Bifury x2 & the other for the AntMiner U3 )
I also have a S3+ 444Gh/s. That is a total of 512Gh/s pulling 445watts at the wall (including the laptop an external drive and a exsyx powered USB hub).
It has bee a big learning curve. I have more than 20years experience in electronics but no real computer experience (well no more than the average housewife has), but I can now write .bat & .conf files. I am also out of work as there is no call for PCB assemblers now that pick and place machines can surface mount components so quickly. I now care full time for my disabled partner who is an army veteran without a pension and is quite unwell. We live on a very tight budget with little prospect of me working again due to my age. If I could find a block, we could have a holiday and eat well for a while and I could afford to see a dentist too.
So... I am looking for advice and this is where you guys come in. Up until now I have had my ~500Gh/s pointing at Slush giving me 10mBTC every 4 days at the current difficulty of 113G . (No holiday there!) So solo may give me a chance?
I am currently downloading the blockchain with bitcion-qt on to a 120Gb external drive with the old Inspiron (currently 3+ days in and now have 28.8Gb on the drive and still syncing... 1 year and 7 weeks to go).
I had planed to still run the S3+ on slush to help pay for the electric and solo mine with the rest via my full node but, I think I have to open port 8333 on my hub once the blockchain downloads - hmmm more to research I guess)
However, now that I have discovered solo.ckpool.org I could point the U3 and Bifury x2s at solo.ckpool.org:3333 or de.ckpool.org:3333 (not sure which one as I am in south west of UK) and use my full node as backup as it will have UPS too... and also give me a some deference against ckpool going down.
Also, I don't know if the 1.7GHz possessor will run the U3 and the Bifury x2s as well as bitcion-qt. Maybe I will run only one instance of cgminer-4.9.2.
I had to shut down the U3 once the blockchain started to download because it had lots of HW errors. The two the Bifury x2s run ok though.
I know this is a ckpool thread and sorry for throwing so many of my problems out here but.... Ideas, critique welcome!
Is a ~68Gh/s solo mining rig futile? Am I just some mad old woman trying to work a miracle with a load of old junk?
I know finding a block is a long shot, but its the best I can mussel up at the moment and my only chance of a holiday for myself and my man.
Thank you all in advance.
Hello greenuser! Maybe I can help. First, thank your husband for his service. His sacrifice is what makes us all free to use BTC and shout at will at whatever gives us grief. A big, fat, thank you.
Now, on to your problems. For solo mining you're going to blow a lot of electricity running a full node and mining on it. If your computer isn't on all the time normally I'd just point my stuff at ckpool and let it run. That will save you some $$$ on the power bill..
If your computer is running all the time you may still have problems since you're running a U3 and the core Bitcoin-qt on a 1.7 ghz machine. That's a lot of work for a small processor. Don't whip the baby. In short, I wouldn't run a full node in your situation.
Now for the "futility" argument - no, it's not entirely futile to solo mine with 68 GH/s. It may never happen though, at least not in your lifetime. Of course it could happen tomorrow. It's like buying a lottery ticket you know. You may win and you may not. You still keep playing
For reference, we had one guy hit a block with 1.5 TH/s a week or so ago. My block was hit with 430 gh/s on an S3 miner with a bad chip, but that was when diff was 51billion and September of 2015. It's now 103 billion and almost 4 months later with no hit.
So in summary you should absolutely run your solo mining rigs but again, don't expect anything for a good long while. It's just gambling right now. Keep your pool mining going as well so you have some income coming in and keep your fingers crossed. And plan wisely for when you win. Luck favors the prepared, Dahling!
