This has got to be the absolute worst way to leak customer data by Revolut.
They sent bitcoin transaction and passport records to a fake government email.
No due diligence at all.
Now criminals know exactly how much bitcoin you have in self custody.
You can’t trust anyone.
@NoahRevoy There is an enormous difference between 1) “one week out of my month I need more rest and to stay on top of my mood swings” and 2) “I am incapable of leadership/doing things men can do.
All women are self aware of their cycle and how it effects their lives, it’s hard to not be.
⚠️ ALERT: Telegram has been removed from the iOS App Store worldwide.
Apple has not provided a reason for the removal, and neither Apple nor Telegram has issued an official statement at the time of writing.
Existing installations appear to remain functional.
people who stored their btc on coldcard got drained because of entropy.
the seed generation was reproducible, anyone could recompute their keys.
so i went through every other hardware wallet to see how they make your seed, and whether the same thing can happen again.
@Trezor: mixes the device's randomness with randomness from your computer, and the device has to prove it used both. even if its chip is fully broken, you're still fine. the best design here by far.
@BitBoxSwiss: 5 separate sources of randomness combined. one bad source can't sink you. open source, reproducible builds, dice supported.
@FoundationHQ: built their own randomness circuit out of plain resistors and capacitors, open source, on top of two other sources. no black-box chip to trust. supports dice.
@KeystoneWallet: 2 secure chips from 2 different manufacturers, combined. also lets you roll 99 dice and publishes how to check the result yourself.
@Blockstream: jade pulls from 7 things: radio noise, cpu counters, battery, temperature, camera, your input, the app. very hard to break all of them.
@SeedSigner: your dice are the only source. no chip to trust at all. and they ship a guide teaching you to verify their own math. weakest hardware, strongest proof.
@OneKey: secure element plus mcu combined on device, open source firmware. solid, but you can't add your own randomness.
@Ledger: one certified chip (AIS-31, EAL5+). good randomness. but it's a single source, closed source, and you cannot verify any of it. you're trusting them completely.
@Tangem: key is born inside the chip and never comes out. audited by three firms. same trade: strong, and impossible for you to check by design.
@ngrave_official: mixes chip randomness with your fingerprint and room light. clever. but the "EAL7" badge covers one software component, not the whole device.
@ELLIPAL: single certified chip, no software fallback, fails closed instead of guessing. closed source, so take it on faith.
@SafePal: 2 chips mixed. they've never published the details.
@COLDCARDwallet: patched now, and dice on coldcard were always verifiable. but every seed made between 2021 and 2026 is permanently burned.
one source = ledger, tangem, ellipal. that one source fails, everything fails. their answer is to make it excellent and certified. that's exactly the bet coldcard lost.
many sources = trezor, bitbox, passport, jade, keystone. one broken source never reaches your key.
and every one of these claims 128 or 256 bits.
coldcard did too. certification doesn't help either, coldcard's chip was fine, the code just stopped calling it.
the only thing that saves you is being able to check.
roll your own dice. verify the words yourself.
🇺🇸 JUST IN: Thune reaffirms the Senate will vote on the CLARITY Act before the August 7th recess.
Monday's Senate schedule had no vote on the bill.
Four working days remain and it still needs 60 votes to clear a filibuster.
The Bitcoin subreddit is absolutely heartbreaking right now.
So many people have been destroyed.
I recommend having a look because it gives you a different perspective compared to X.
Really sad.
I’ve been part of the @rekt_gang community for a little over 2 years.
In 2024, I bought my first Rekt Wolf on ETH, then eventually ended up with 2 (thanks @LensInkMouse for the OTC on that clean gray wolf!)

@joe4deadcat Isn’t it also because billionaires have infinite leverage, both from making unique inventions (Google, FB, AI, etc) and also from leverage at the bank? There is no ceiling on how much money you can make when you are wealthy but there is one when you just take a wage,
NSW brewery @HawkesburyBrew has been making headlines over the past 24 hours.
Operations Manager Adam Neal said the brewery uses excess solar energy to power liquid-cooled Bitcoin miners, with the recovered heat then used in brewing operations. The system is currently generating around $2,000 worth of bitcoin each month.
“If you can utilise the heat for some sort of purpose… for heating, that’s fantastic,” said Professor Sean Foley, Professor of Applied Finance at Macquarie University.
Bitcoin mining is increasingly proving to be more than just a source of revenue. For businesses with surplus energy or a need for low-cost heat, it can become another tool to reduce operating costs, improve energy efficiency, and strengthen the economics of their operations.
The Australian Bitcoin Industry Body looks forward to more Australian businesses exploring how Bitcoin mining can turn wasted energy into lower costs and greater competitiveness.
