Exactly! Health is the real treasure.

Sure, we can demand KYP, but how do we enforce it? They won’t comply.

Sorry, I typed that out on my phone. Check this code. It'll help clarify.
In crypto, influencers don’t lose their reputations. Even if they did, I doubt many would care as long as they make bank. Richard went from rekt to multi-millionaire. Ethereum's got POS coming, where real Ether can be…
- Is Richard Heart just another crypto scammer?Jun 29, 2025
It's funny (but not in a good way) to see Bitcoin maximalists like Tone Vays and Peter McCormack call out Richard. They're just giving him free exposure. It's so obvious this is a scam, yet they debate him. All Ether…

Thanks everyone, really grateful for all this info! I'm kind of stuck with the external SSD now but planning to upgrade soon. The problem did happen a few more times, but luckily no corruption yet. Eventually got the…

Appreciate that advice. Seeing "fatal" made me panic. Gonna try what you suggested and let you know how it goes.
- Fatal Error While Downloading Bitcoin BlockchainNov 15, 2023
Thanks for the reply! Should I just restart BTC Core? Can I resume the download where I left off, or is it a complete restart? Not sure what the next step is.
- Fatal Error While Downloading Bitcoin BlockchainNov 14, 2023
Running Bitcoin Core 27.1 on Linux Mint 22, got this Intel i5 with 16GB RAM and an external SSD. Was downloading the blockchain, but then suddenly got a fatal error... like 7 hours in. Now, my SSD just vanished. Had to…
- Do we really need regulation for cryptocurrency?Feb 27, 2023
But does it even matter? The government is gonna regulate crypto whether we like it or not. Can’t really stop them.
Dude, this is more about politics than actual legality. It’s just rich guys bickering over who gets a bigger slice of the pie. They’ll probably hug it out later.
- Hacking Justice: Jail Time for Malware CreatorsAug 29, 2022
Right, criminals have a short shelf life. They may steal but they rarely get to enjoy their ill-gotten gains. It’s all a big mess.
Your insights are impressive. I’ve just started learning about options and your breakdown made it much clearer. Appreciate your effort!
Stick to the main wallets like Electrum and blockchain.info, and forget the rest. Too many fraudsters lurking around.

Sure, here’s a snippet: from ecdsa.ellipticcurve import Point from ecdsa.curves import SECP256k1 # Secp256k1 parameters curve = SECP256k1.curve p = curve.p() n = SECP256k1.order G = SECP256k1.generator # Endomorphism…

Endomorphism is the key here! You can generate multiple public keys from one point using some constants. Got a script that does it all in one go.
Just remember, we’re working with the pubkey as our known variable. No decimals or private key involved.
In secp256k1, 1/2 gives a huge number. Just checking if that method actually helps with odd/even pubkey definitions. Tried a bunch but patterns stay the same.
Wait, what’s the connection with scalar parity and y being odd/even? It seems like there’s no proof either way. Maybe a super-computer will figure it out someday.
So, what you’re saying is there’s no positive or negative? All numbers are technically positive?
