So recently I saw a  post on social that someone mined a block with solo mining and get reward 3.125 BTC
Does it worth to go Solo Mining or should I stay on pool and get enough to pay the electricity and a bit profit !

What is the hash rate the miner is generating that he used to mine a bitcoin block? What could be the cost of the miner that the miner is using before he was able to mine a block.

The hash rate is not small at all but there are solo miners that are mining blocks often but we do not have enough information about them to know if truly they are solo miners or not as people can decide to join hands in something without joining a mining pool.

To be a solo miner or not will depend on your budget. If you are a millionaire and you are ready to spend millions of dollars on buying miners, solo mining can be for you. If you only have thousands of dollars to spend on mining, joining a mining pool will be better.

You should check your financial capacity if it will be able to cover up the cost of solo mining both electricity bills, cost of overhead and maintenance. You should also know that involving in solo mining isn't a guarantee that you will be in profits, because the chance of solving a block puzzle is very slim due to small computing power.

If you are with a mining pool, the chance of making profits is higher because of high computing power from various individuals and they can mine a block faster than just one miner and mining is a competition.

unless you have a lot of hash power, mining alone is very dangerous. because mining pools provide more regular, predictable payouts, even if they are smaller, the majority of users stick with them. basically there is a trade-off between low risk and low reward (pool) and high risk and high reward (solo). maintaining a pool is typically the more practical and smart option, especially when electricity costs are taken into account, unless you're operating an industrial-scale mining operation.

Does this mean it is not suitable for individual mining but is suitable for large mining farms?

The common answer is no.

Total hashrate that a person have usually is too low to have acceptable chance (for example, 1 block per 1 months) to mine a block alone. In addition, mining difficulty is expected continue to rise where your chance become lower over time.

No it's not worth to solo mine unless you have better equipment, the higher your total hash rate the closer you get to solving a block, right now you need 1EH to solve a block faster.

If you have a never ending electricity then you can buy a solo miner and plug it away, go back to your normal life and maybe one day you will hit the jackpot, many people are doing this but the majority will never solve a block.

Make sure you risk money you are ready to lose because once you purchase the equipment your money isn't coming back, the chances that you will never solve a block is incredibly higher.

We've discussed this many times, and according to probability theory, you have a better chance of winning the lottery than mining solo on 1-2 ASICs. Someone always wins the lottery too:)
The ideal model is when you pay off your equipment and play lottery mining on free hardware.

You didn't mention what miners you have because if you're talking about power-hungry units like S19 or any Bitmain units, I don't think you can survive paying the electricity bill for a long period of time. The chances of finding a block are very slim if you just have a few of these units, plus you would spend much paying your bills.
If you have a free power source, maybe it's worth it to do even with a single unit and point it to solo mining. But if it's not free, it's better not to do that because it would cost much. However, if you still want to try solo, I guess you better try lower-power units like USB ASICs, like block erupter or BitAXe units are much cheaper to run.

Really, he got 3.125 BTC for mining a block? Then I would say he is a lucky miner. It's not easy to mine a block alone as a solo miner. Because rewards really depend on the hashrate compared to the entire Bitcoin Blockchain hashrate. For a solo miner, the chance to mine an entire block is extremely low. I really don't want to trust social media posts. Anyone can write anything they want; it doesn't make sense to trust everything there. Because it's kind of unrealistic to mine an entire block without a big mining farm.

On the other hand, mining through a pool would be better for a stable income. But for that you can't calculate the energy cost in your country. Also mining should be legal where you intend to set up mining equipment. Remember, a solo miner would have to wait longer to mine a block and really wouldn't know whether he would succeed or not; it's like a gamble compared to pool mining. Most small and medium miners join the pool for mining Bitcoin.

305th solo block

Congratulations to miner bc1q~nwsgdw0wfh4trqal69fz with 9PH for solving the 305th solo block at http://solo.ckpool.org! A miner of this size has about a 1 in 800 chance of solving a block per day.

That's not a solo miner, that's a large farm running by a rich personal😂. They know that they will solve the block easier and faster using that much hashrate, the money they use to set up that hashrate and even the electricity bill is going to be massive. Richey favours those who have money, because it's obviously that they will always have the upper hand in everything, one single good move is all they need and they will make it worthwhile. I am even thinking that 100TH will soon be useless for those solo miners, if I want to do this I would rather start with 500TH, solving a block is the goal not playing for luck in the casino.

Before you consider solo mining, you should first consider the potential risks, such as the cost of mining equipment, electricity costs, and calculating how long it will take to recoup your investment. Bitcoin mining requires a high hash rate and consumes significant electricity, so be aware of these factors. There may be other costs as well, such as equipment maintenance costs, internet network costs from the provider, or additional costs may be required to create a backup power supply, such as setting up solar panels. Therefore, if you find yourself unable to do so, it is best to stick with pool mining.

Furthermore, there are also potential risks, like mining taxes or regulations. Like in my country, Bitcoin mining is subject to government taxes and regulation regarding to it.

Apart from all that, I think you also need some other references regarding Bitcoin Solo Mine : Bitcoin.org - Mining (https://developer.bitcoin.org/devguide/mining.html) & TheMiningFuture.com - How to solo mine Bitcoin (https://www.theminingfuture.com/how-to-solo-mine-bitcoin/)

By the way, is the news (https://cointelegraph.com/news/solo-bitcoin-miner-371k-block-reward-august-2025) that I and you read about a solo miner who managed to get 3 BTC the same? Because I noticed there was a slight difference in the amount between them, you said the solo miner earned 3,125 BTC, while the news or article I read was 3,137 BTC.
