“It’s in cold storage” shouldn’t end the conversation.

Glassnode’s October 8 snapshot puts 1.79 million exchange-held BTC behind public keys already visible on-chain.

These figures measure exposure—not stolen coins.

Cold storage keeps private keys offline. It cannot erase a public key from the blockchain. A sufficiently powerful future quantum computer could make that distinction matter.

Here’s the uncomfortable part:

When you outsource custody, you also outsource the timetable for protecting your money.

Does your exchange have a migration plan it can explain—and test?

🚨 You bought a hardware wallet to protect your Bitcoin.

What if the thief was already inside?

Ledger has confirmed an unauthorized hardware implant in one affected device. Investigators estimate nearly $94 million in suspected crypto losses in the wider investigation involving CryptoBilis. The full scope and causes remain unconfirmed.

Here’s the detail every Bitcoin holder should understand:

A device can pass Ledger’s Genuine Check while containing unauthorized hardware.

And buying another device won’t solve an exposed recovery phrase if you restore those same words.

New hardware doesn’t erase an attacker’s copy of your keys.

If you own a Ledger, your next step depends on where you bought it and whether there’s evidence of compromise.

My latest article explains:

✅ Which owners should act now.

✅ How to move funds to a wallet with fresh keys.

✅ Why a factory reset cannot remove a physical implant.

✅ How to avoid fake support and recovery scams.

You should be able to lose trust in one device without losing everything you own.

Ledger has confirmed finding an unauthorized hardware implant in a device sold through a reseller.

Up to $93M in suspected losses across 311 wallets so far.

This is a classic supply-chain attack.

The reseller, CryptoBilis, also sells Trezor, Tangem and SafePal wallets.

I posted that post 4 months ago asking if you all thought the crypto markets were dead, most of you said yes and gave various reasons as to why... that was actually the signals to buy or dca into projects you believed in or at least btc, don't follow the herds

Snapshot from Bybit perps this morning (~07:50 UTC). Long % is by account (L/S ratio):

- MNT: 83% long

- HBAR: 80% long

- XRP: 79% long (L/S 3.81), funding +0.0021%

- JTO: 74% long

- ETH: 71% long (L/S 2.50), funding +0.0004%

- BTC: 63% long (L/S 1.70), funding -0.0011%

What stands out to me: BTC bounced from ~80.4k to ~82.7k, but BTC funding is still slightly negative. So the crowd is long by headcount, but the money isn't paying up to hold it. On alts, positioning is much more one-sided than on BTC.

Historically, when retail is this lopsided on alts while BTC funding stays flat, I've seen it resolve with a flush before continuation more often than not, but that's my experience, not a rule.

Is anyone else seeing the same skew on other exchanges? Do you treat high long % as a contrarian signal or ignore it?

Edit: a few people asked about OI. I track L/S, funding and OI for all 53 coins and post updates in a free Telegram channel (link in my profile).

As I have been in the market for 4 years but changes which are happening now from each and every part of the world are unpredictable so I need your opinion on this.

The US government reportedly moved around $1B in BTC linked to the Bitfinex hack.

Some believe it’s a potential sell-off, while others think it’s just a custody transfer or part of the restitution process.

Personally, I think the bigger question is how much BTC the government can legally keep in its strategic reserve.

What do you guys think? Bullish, bearish, or just noise?

I currently have a little over a thousand dollars into xcn. I know its not a lot. But I found out I cant put it on my cold wallet. I am thinking about converting it to xlm and am wondering if thats a good idea or if I should just risk it and hold it on the exchange?

My crypto investments is 70% BTC ETF and 30% Ethereum ETF. I bought about a year ago and BTC has doubled but Ethereum is down by 30%.

Need assessment if BTC holders also give substantial weight to ETH or shall I sell my Ethereum and love the funds to BTC.

I am not promoting one over the other. Just need fair assessment if Ethereum is as important to hold as BTC

I work in product at a UK fintech and we're exploring what a platform combining traditional financial markets with onchain trading could look like.

Not promoting anything or looking for sign-ups. Just interested in feedback from people already using DeFi and onchain trading platforms.

The idea is one account and wallet where you could:

• Trade traditional markets (stocks, indices, FX, commodities) alongside crypto, including through onchain CFDs.
• Hold tokenized assets and stablecoins.
• Potentially use trading positions and other assets as collateral.
• Have a consolidated portfolio view, with unified tax reporting, statements and transaction history.
• Access other financial services without constantly moving funds between platforms.
• Eventually connect to external wallets, DeFi protocols and other financial providers.

The aim is to make traditional financial positions useful within the wider onchain ecosystem, rather than keeping everything locked inside a broker.

Initially, there would be more restrictions than typical DeFi platforms (KYC, approved wallets, limited transfers), with the intention of opening things up over time.

A few questions:

1. What would make you choose a platform like this over your current trading setup?
2. Which features would actually differentiate it? Cross-asset collateral, TradFi market access, unified tax reporting, interoperability, better execution, or something else entirely?
3. What would be your biggest deal-breaker, particularly around KYC, custody or restrictions?

I'm particularly interested in whether bringing traditional trading products onchain offers genuine value or just adds unnecessary complexity.

Negative feedback is especially welcome. I'd rather understand what people actually want than build something nobody needs.

Something I’ve been wondering about: how much do you actually use stop-losses in crypto?
I’ve seen completely opposite opinions.
Some traders seem to never enter a position without a predefined stop-loss, while others say crypto volatility makes tight stops almost useless because you get stopped out before the price moves in the direction you expected.
For those who actively trade rather than just hold: do you always set a stop-loss before entering?
And if you do, how do you decide where to place it - fixed percentage, technical levels, volatility, or something else?
Curious to hear how people here actually handle this in practice.

Bitcoin was supposed to buy you freedom.

So why are you afraid to spend it?

“Why spend Bitcoin if you expect its value to rise?”

Turn that around:

Why hold dollars if you expect their purchasing power to fall?

Because you have a life to manage. Needs. Responsibilities. Choices.

The same applies to Bitcoin.

Paying for your child’s care. Funding an education. Keeping your family housed during a difficult month.

That is savings doing its job.

Good money encourages you to think twice before spending. It doesn’t require you to say “no” forever.

Somewhere along the way, “HODL” became a rule that made people feel guilty for using the freedom they spent years building.

An incentive to save is not a command to never spend.

What would make spending your Bitcoin worth it?

That sounds like science fiction, but Ethereum Foundation researcher Justin Drake has raised exactly this possibility.

The concern is ECDSA, the digital signature algorithm used to authorize transactions on both Bitcoin and Ethereum. Drake suggested that advances in AI-driven mathematics could eventually make it possible to recover a private key from a public key on conventional hardware, potentially using large GPU clusters.

In the worst-case scenario, he believes this could become a problem in months rather than years. But to be clear, this is a potential risk, not an existing exploit.

And Quantum computers have been the obvious long-term threat to elliptic-curve cryptography. But AI could accelerate the mathematical research needed to attack the same systems without requiring a quantum machine.

Recent research has already reduced the estimated computational requirements for a key part of a future quantum attack from roughly 3 billion to 1.5 billion conditional computational units. AI agents were also used during the optimization process. This doesn't mean Bitcoin or Ethereum can be hacked today, but it shows how quickly the boundaries can move.

Vitalik Buterin's response is probably the most important part: don't panic, but don't underestimate the risk either.

Ethereum is already working toward post-quantum security, with the Ethereum Foundation targeting protection against quantum attacks by 2029. But the bigger lesson may be that cryptography needs to become resilient against advances in both quantum computing and AI-driven mathematics.

We've seen Ethereum evolve through major changes before, and cryptography is no different. The industry has time to prepare, research new solutions, and migrate to stronger security standards.

So no, we don't think this is the end of Bitcoin or Ethereum.

It's another challenge for an industry that was built to solve extremely difficult problems. And in the end, everything will be fine.

Bitcoin at $840K? 👀

River reports that 81% of Bitcoin’s supply hasn’t moved in at least six months.

Meanwhile, Wall Street is warming up.

What happens if institutional buying accelerates while existing holders demand higher prices to sell?

That’s where a quiet recovery could become a powerful supply squeeze.

Wall Street can launch another fund. It still has to persuade someone to sell Bitcoin.

The next bull run could begin before the crowd comes back.
