1) What kind of tools/hardware/software/equipment I need if I want to mine A) 1 bitcoin/day B) 1 bitcoin/month C) 1 bitcoin/year in my home alone?<p>2) Anyone did this setup at home/ "here in my garage"?<p>3) Is it possible to create "smart" algorithm to reduce computing cost per bitcoin?<p>4) How do I locate all locations in the world who are mining right at this moment? heat signature? power surge?<p>5) How do I "VPN/mask" my mining so no one can know that I doing bitcoin mining "here in my garage"?<p>Thanks :)
Bitcoin miners use specialized hardware designed for mining. There is no special algorithm to make mining faster or more efficient and that is by design. Bitcoin is meant to take a lot of work to mine. Bitcoin also adjusts itself automatically so that each mined block takes roughly 10 minutes to find. There is no avoiding this.<p>The specialized mining rigs are very expensive and they have facilities with thousands of them running in parallel. It hasn't been feasible to mine bitcoin as an individual since around 2012. You can still do it though, but the odds of you finding a block are so infinitesimally slim that you're basically wasting all your time and money. You could join a pool, but with so little computing power your share of any reward will be incredibly slim. Sadly, I do not recommend trying to mine any cryptocurrencies.
I did this in 2018. I bought an Antminer S9 and power supply. It's not worth it as an individual. In order to earn anything at all, your cost of power needs to be ludicrously low and you still need to join a mining pool.<p>And these things are LOUD. After a year of mining I broke even.
The biggest problem you'd have is energy cost. Bitcoin (and proof-of-work cryptocurrency in general) mining is very competitive which means the profit margins are super-thin and you're competing with people who get their energy very cheap, possibly even illicitly.
> 3) Is it possible to create "smart" algorithm to reduce computing cost per bitcoin?<p>I think this is equivalent to the problem: "how can I calculate SHA-256 hashes more efficiently?"<p>This is an open problem in cryptanalysis. Is it "possible"? I think so, but it's a very complex computer science question. I would say: "it is probably possible, but extremely difficult to the point that it might be impossible."
The only point to mining Bitcoin yourself is tax avoidance. You can make back the cost of power and equipment over time, basically hiding your income. I suspect this is the main reason that people mine crypto. You won’t make a profit. It’s the tax you save through tax evasion.
The fan noise is far too loud. You need a garage that is detached from your house and very far from your neighbors or you will get noise complaints.<p>1 BTC/day is 200,000 TH. ~15k ASIC miners.
Bitcoin mining has a "variable" difficulty. If many are mining, the difficulty rises a lot. Any many many are mining Bitcoin.<p>See <a href="https://www.nicehash.com/profitability-calculator" rel="nofollow">https://www.nicehash.com/profitability-calculator</a> in order to figure out whether your investment (buy the mining equipment, pay for electricity) would be able to break even.
My understanding is this isn't really feasible these days. Bear in mind that the 6.25BTC block reward is currently worth about $300,000. There's a lot of competition and most of it will be investing enough to get economies of scale not obtainable for garage-scale miners.
Interestingly, I was just looking at the requirements for mining ETH.<p>But I still don't know why I'd ever need a ETH coin (other than as a store of value). Why would someone buy a ETH coin from me?<p>I may be talking nonsense, but if for example, my employer decided to switch from paper wageslips to an ETH contract, would I need ETH to execute that contract and receive my wage?
Drawing large amounts of electricity can raise suspiciouns. Such as law enforcement suspecting you run a marihuana/hemp operation.<p>I recommend against mining for different primary reasons though. It is speculation and bad for the environment.
The "trick" is finding a good spot where you can build a small hydroelectric power generator. Then you just convert the electricity into money. I'm not sure about the current conversion rate, but it's generally the average price of electricity that is used to mine bitcoin.
Now is definitely the time to jump into crypto. Tesla just stop excepting it. It cost $8000 dollars in electricity to mine each coin. Using cheap coal fired generated electricity seems to be the way to go. Who cares if the world chokes on the CO2 as long as you're rich right?
