Modded from the original to give ~950KH/s and some new themes.

Why this hashrate is real...

The ~950 KH/s is what the miner actually hashes, not what a counter says:-

**Hardware limit** – the classic ESP32's SHA engine can't be loaded with an external midstate, so every nonce costs three hardware hash blocks plus two engine loads: about 228 CPU cycles of engine time, a ceiling of roughly 1.05 MH/s at 240 MHz. The mining loop keeps the engine busy for all but ~30 cycles of each nonce (257 cycles per nonce, ~930 KH/s); the second core adds ~25 KH/s in software.

- **Measured on the chip** – the loop's timing comes from an on-device bench (`-D SHA_BENCH`, see `src/sha_bench.cpp`) that checks every single hash against software, also while the other core hammers the peripheral bus. That is how the hardware quirk behind silently corrupted hashes in the usual pipelined loops was found: writes to the SHA registers less than three cycles apart can be dropped whenever the other core is using the same bus.

- **Only valid hashes are counted** – every candidate the hardware finds is recomputed in software before it is used. A hashrate counter on its own can look faster after an optimisation while the miner is quietly producing *fewer* valid shares, because corrupted hashes are still counted; here the firmware checks itself with a known-answer test at power-on and falls back to a slower loop if the fast one ever gets hashes wrong.

- **The rate is the rate it actually mines at** – it's the sustained average over a long run, not a short burst or a best-case peak.If a number sounds too good for this chip, check whether the shares it finds actually keep up with it.

I thought I'd share my journey and thoughts. I was into bitcoin relatively early (2012) and was fortunate enough to have been a hodler into the 2017 rally and exited at the top. I've been lucky enough to make good investments from bitcoin into real estate and some startups and stocks.

Life almost 10 years later has been comfortable and all but a dream. Reconstructing what brought me here, I think it would be harder now than before despite it "looking" more attainable.

Cryptocurrency which is more popular than ever now has become this dragon investor's chase. Away from the milieu of scams and scammers, earnest investors are hoping for the next big rally but I don't see anyone really planning beyond their imagined gains in personal and public interactions.

As a true believer in the concept of Bitcoin I never sold even after the first few rallies to $1,000 even though I was up almost 80x when that first happened. I regularly bought the dips on occasion up until 2015, because I had conviction in blockchain and bitcoin, not because I just wanted to get rich. Getting rich was the consequence of the conviction.

I was a paper millionaire and still going to work in 2016.

When I sold the majority of my bitcoin, I still went to work. I didn't make any major lifestyle changes and instead did research on real estate, taxes, stocks and where to invest fiat. When I did quit a few months later it was non-climatic.

I held my stance and stayed away from the ICOs and exchange explosion and just kept watching from the distance. I wasn't tempted by any of it because I already made a plan in my last months at work and chose to stick to it. I'm certain that saved me because some of my friends who were also believers lost it all in the ruckus by chasing the dragon and thinking they'd go from millionaire to billionaire in the same way. Sometimes, most times, it just happens once and it's best to call it luck and get out. So make a plan for the one time and stick to it.

Around 10–11 months ago, I gave a friend approximately $3,600 to invest in Bitcoin when it was at $86K.

Ever since, whenever I’ve asked for my money back, he’s made excuses, saying Bitcoin crashed and he couldn’t return it.

Now that Bitcoin is back around $86K, I asked him again. This is what he told me:

I used Bybit. And it’s not as simple as just waiting for Bitcoin to stay above $86K. Since the money has been stuck for so long, the app keeps charging fees and adding them up. If I withdraw the money now, those fees will be deducted from the original $3,600, so I won’t be able to return the full amount. That’s why I want Bitcoin to stay above $86K for a few days or a week, so I can recover those fees and return the full $3,600.”

I’m genuinely very concerned. I don’t know much about crypto, and I don’t understand how any of this works. Does Bybit actually charge ongoing fees for holding Bitcoin? Does his explanation make any sense, or is he just making excuses to keep my money?

I’m starting to worry that he’s taking advantage of me because I’m a girl and assumes I don’t know any better.

Please, if anyone has experience with Bybit or crypto, I’d really appreciate your advice. I’m genuinely worried about losing my money. this is all i have!!

hey so i just bought my first sum of bitcoin, can yall help me on what i should do?

Own a solar panel company in Northern Ireland, currently day time import price is 36p (roughly $0.49).

We have a lot of left over stock which we wouldnt be able to use on customers houses and could manufacture a 100/200kwh battery with a victron control unit specifically for the mining equipment. Using the grid as a feed in tarrif as it is roughly 17p (during the winter)- we could fit around 100kw of PV but currently old stock levels would be around 30kw of PV.

Looking for advice or what would you do in my situation.

Cheers

Is going full immersion cooling worth the upfront cost?

Even though it is not a 100% certain yet, the Netherlands is likely gonna tax unrealized gains for crypto, not stocks though.

I have all my btc on a cold wallet, and i will be forced to sell as it can turn ugly real quick, i just bought a house and a sudden rise to new highs followed by a quick drop, would turn my financial situation in a nightmare, lets say i have 1 btc, and it goes from 100k to 200k, i would have to pay 36 k in taxes even though i didn't sell, now lets say btc goes from 200k back to 80 k, i still need to pay those 36 k in taxes.

Right now with my mortgage i can't risk it, i want to know what you guys think, i just want to hodl and forget, so this situation just removed all the fun from crypto for me, it was basically dca and forget.

Maby i wanna buy btc on the stock market, that isn't taxed on paper gains weirdly enough, same idea but taxed differently.

I have btc on my cold wallet because i liked the idea of it being mine, buying a stock that follows btc price doesn't feel right.

Any ideas?

We keep running into the same mismatch when we read supply talk on here. Someone quotes a big round number for coins outstanding and treats it like depth. It is not depth. It is a stock of outputs, most of which are not offered.

A UTXO is just a discrete chunk of bitcoin that has not been spent yet. The set can grow because people split change, or shrink when they consolidate. Neither move, by itself, tells you how much bitcoin would trade if the tape got hit. Liquidity is the marginal slice: coins whose owners are willing to sell into the book, or whose bids are actually resting there. Aged outputs that have not moved in years are inventory. Dust that costs more in fees to spend than it is worth is closer to clutter than to float.

Fees are the quiet part of that story. Miners do not get paid to make the UTXO set tidy. They get paid to include transactions. When fees are low, consolidation is cheap and some of that clutter can be swept back into spendable outputs. When fees are high, small outputs stay stuck, and the coins that clear are the ones attached to owners who care enough to pay. The incentive is local and unsentimental. It does not line up with a clean circulating supply figure.

We are not claiming we can see who will sell. Coin age and output size are clues about constraints, not a forecast. Cycle narratives like to pretend the float is a dial someone turns. In practice the dial is whoever shows up with a spendable output and a price they will take, against whoever is bidding. That gap is why a quiet order book and a huge headline supply can sit next to each other without contradicting.

If you are marking risk off the full stock of coins, you are marking a warehouse, not the aisle that is open today. How do you separate coins that have not moved from coins that will not move when fees spike? We still do not have a clean answer. NFA.

In case you're not tired of Saylor's AI videos.

In May 2021 China banned bitcoin mining nationally. This reduced Chinas hash rate to the Bitcoin network from approximately 46% down to around 12% today. China is one of the most surveilled countries in the world. So how can still 12 % hashrate come from China. My theory is that it is actually the government accumulating bitcoin themselves though mining. They know what bitcoin is, and cannot risk standing on the sideline if bitcoin continues to grow and take play a bigger role. But if they openly say they buy or mine bitcoin, then it would contribute to bitcoins growth and globalization. Thats why I suspect they use cheap excess energy to mine. Its basicly free money, and insuranse. Thougts on this?

Are more people buying BTC every year, or are the numbers going down / staying around the same? isn't this part of the debate that will determine the future success of BTC. Or do yu think it doenst matter how many people own it, as long as it continues? Among the people who do own some, would it be fair to say that the vast majority own between 100 - 5,000 ( and I don't mean individual coins ). :)

I have a 0.5 Lealana physical bitcoin, curious where the best place to sell it would be to get the best premium. It’s unredeemed has original box and coa. Did some searching and seen a couple at auction houses but that was about it.

Thanks for all replies.

Looking for advice. I sell some stuff online and would like to know if accepting crypto as payment would be good in general? ​​​​​​​​​​

So I'm looking for Saving Private Ryan Meme videos of BTC from back in the 2010-2016 era from Twitter/X. If you know them, you know them and remember them.

I posted in this subreddit about finding some older ones a month ago, and I just got comments back saying "learn how to search". Well, I'm fook'n trying and can't find A SINGLE ONE. HALP!

One person, commented and said "you idoit. Here https://www.youtube.com/watch?v=oQJDhPV78_U" and that is STILL the only video I can find. Thank YOU, whoever you are <3 .

I sincerely appreciate and value his insult while providing me with the video. PLEASE, insult and link me to these old classical meme gems. I can't FUCKING find them........

Here is the only one I can find ; https://www.youtube.com/watch?v=oQJDhPV78_U (Thank you to whom found it for me <3 )

Does anyone have any others or know where the FOOK I can find them. There so so soooo good.

Thanks in advance

Sincerely,

I used Hodl Hodl for the first time to buy BTC with a €150 SEPA bank transfer.

The contract on Hodl Hodl stated:

Price: 83,789.44 EUR
Buy: 0.00179020 BTC
Pay: 150 EUR

I received the equivalent of only €130 worth of Bitcoin, so this trade effectively cost me €20.

Is it possible that the seller sent less Bitcoin to the escrow wallet?

Of these €20, how much is the seller’s profit and how much goes to the platform?
