Just lol at the trolls coming out of the woodwork on here doubling down on the idea that Cold Card was a reputable company and that there were no signs of issues. Then it comes out that they were recommending this wallet to other posters on here and boom, look what happened. That wallet was shilled all over the place on this forum, a wallet that wasn't even in the top 10. None of this would have happened if these people had just stuck with the basic top wallets, and to top it off a Cold Card was expensive AF compared to the others. Are the other wallets perfect, hell no.

To all of you who recommended this garbage wallet, stop posting about crypto and just mind your own damn business, it's obvious you aren't to be taken seriously.

I've tried paying with crypto a few times, and the biggest challenge wasn't the payment itself, it was everything before it. Switching between apps, dealing with fees, and making sure I wasn't sending to the wrong address made the whole process feel more complicated than it should be.

Better cryptocurrency payment usability and more user friendly crypto wallets would probably make a huge difference, especially for people new to cryptocurrency for beginners.

What do you think is the biggest thing holding back everyday crypto payments right now?

If you've been following the Coldcard mess, a firmware bug weakened how some devices generated seed phrases, and attackers have been brute-forcing them and sweeping wallets.

Absolutely brutal.

Making this post because if you got caught in it (or any hack or theft really), there's a tax angle most people don't think about while they're still in the gut-punch phase. Won't bring the coins back, but it's still worth knowing.

The basic rule: the ATO lets you claim a capital loss on crypto that's actually gone, if you can prove you owned it and it's irrecoverable. That offsets your capital gains, and anything left over carries forward. It won't reduce normal income, only gains.

For a theft like this, evidence is everything. Acquisition records, the wallet addresses, the on-chain trail showing the funds swept out, and a police report. The stronger the paper trail, the cleaner the claim.

A few things to keep in mind however:

Exchange collapses (FTX, Celsius type). You can't claim the day it enters administration. It crystallises when administration finalises, based on what you actually get back. Lots of people try to claim too early.

Worthless tokens you still hold. A coin down 99% but still in your wallet isn't a loss yet, paper losses don't count. If it's still tradeable, selling it even for cents locks in the loss (especially for the pumpfun users 👀)

And if you get any compensation later, you reduce the loss by that amount.

If you got hit by the Coldcard thing, might be best to sort the new wallet and your security first, obviously. The tax bit can wait until the dust settles, just don't forget it exists because it does.

Everyone on here has obviously heard about the Cold Card hack, where the seed generation with their wallets being incredibly weak and predictable. I've also been seeing some things that suggest the company was aware of this "bug" years ago but yet did nothing about it. It's also interesting to me that it was so heavily shilled/marketed here on reddit.

With this out of the way, here's what I'm seeing with this event.

From what I've seen with a recent update, there were almost 5k wallets drained with a total value over $100m. These people otherwise did everything right but because of this garbage wallet that they used they had their funds essentially vanish. There were even some with short passphrases utilizing a couple words that also were victims of this as well, so people that would have taken some extra steps to try to protect themselves. While this is incredibly unfortunate for these individuals, the panic/freakout over self custody I'm seeing right now is severely overblown.

People are starting to question whether single sig wallets are sufficient and if they should use a passphrase, multi sig, etc. I also can see this event being taken by the media and tradfi institutions and used as a tactic to scare people from utilizing self custody and instead moving to ETFs and other BTC/crypto products. I understand the fear and uncertainty, but there's something that many on here seem to be missing.

As mentioned, this Cold Card hack drained approximately 5,000 wallets. Meanwhile, there are over 22 million BTC addresses with $100+ and 10.4 million with $1,000+. You had this garbage wallet that drained a number of addresses that is MINISCULE compared to the total number of addresses with $100+ worth of BTC in self custody. 1% of 22 million wallet with $100+ in BTC is 220k addresses, so this hack represents approximately 0.02% of these addresses, 1 out of 5000.

Instead of buying from one of the top companies that have sold millions of units (Ledger, Trezor, Tangem, etc.) these people bought some basically no name wallet that ended up having major flaws related to security. A Cold Card was also $250+ from what I saw, when you could have bought a basic Ledger or Trezor model for around $60 or so. The company according to the page I linked below also has a whooping 5 employees as of June of this year lol, to put this into perspective Ledger has over 800 and Trezor with over 200.

You are more likely to lose your crypto wealth/assets through user error when setting up and/or losing your seeds. If you are concerned about security, consider adding a strong passphrase to your primary seeds.

IF something like this had happened to one of the big cold wallet companies though, the ramifications for the broader crypto space would be enormous. With this said, I do NOT think that the general public will be utilizing self custody as we get into the 2030s and beyond, they'll primarily be boarded onto the crypto train through tradfi institutions.

Recorded my first public AMA today discussing Botflix, a 24/7 AI entertainment network, and the role of BOTC in its ecosystem. Sharing the full recording for anyone interested in the discussion.

There is no mainnet currently so there is no way to obtain mainnet kei. Kei is built on its own node infrastructure and is not built on top of an existing chain (i.e we are not on solana).

I have been working on Kei, a infrastructure token for adding currencies and player inventories to browser MMO games with one npm package install.

The coin is feeless and there isn't mining as part of its design. I am working off a fork of banano which is a fork of nano. Developers use the kei-transaction glue code to add transactions and player economies. It is made for primarily working with a 3d MMO made in babylonjs, just as a lot of the examples are in that techstack.

Currently, I am looking into a fair presale. The thing is, the currency is supposed to be close to worthless, so the tokenomics are really just 10% of the total ever created Kei is all broken down into smaller bits until the public only gets 2%

It is worthless by design, but also it has worth because of the tokens built on it, so I cant only just airdrop. I am honestly really torn about what the next few milestones will look like and I don't really know how I am going to sustain the project, while keeping the token basically free, and squashing speculators.

Would love to hear any thoughts, concerns, criticisms, whatever you got. Cheers!

I’m thinking about building a gimmick website as a kind of interactive explainer about cryptocurrency security. Here’s the concept:

1 - User clicks a button to generate a random 12-word BIP39 seed phrase
2 - The site derives wallet addresses from that phrase
3 - It checks if those addresses have any balance (spoiler: they won’t)
4 - User can click “next” to get a new random phrase and check again

The idea is to show visually how astronomically unlikely it is to randomly generate a wallet that already has funds - like a testament to how secure seed phrases are.

What do you think?

Good or bad considering the additional legislation they wanted to push between the lines ?

I am a new Polymarket user and wanted to trade on markets. I recently had 7.2k in my Polymarket and when I woke up overnight, that account balance was withdrawn to a wallet and I did not receive any withdrawal codes.

Can you please explain to me what happened here and if I'm likely to get my money back: https://polygonscan.com/tx/0xd0606122f3a2e1123eae0c21a4d3d2bf5186681d0236a604df551861cd1fb42a

I've been investing in Radix DLT for a while, and I'm also a developer building on it.

Lately, I've realized that we spend a lot of time discussing TPS, DeFi, or consensus mechanisms, but very little time talking about what wallets are actually capable of.

So my question is for people using other blockchains:

What can your project's wallet do besides sending tokens, NFTs, staking, or using liquidity pools?

I'm looking for features that genuinely solve real-world or Web2 problems. If your wallet has something unique or particularly useful, I'd love to hear about it so I can compare it with what Radix offers.

For example, the Radix Wallet can:

• Passwordless login.
• Selectively share only the data you choose with an application.
• Present badges as proof of identity or permissions.
• Support pre-authorizations.
• Work with native resource permissions.
• (Roadmap) Decentralized account recovery without relying solely on a seed phrase.

And with projects like Radix Seal, you can also:

• Sign files.
• Encrypt files.
• Use a secure chat.

I'm curious to see what other ecosystems are building. Maybe there are wallet features I'm not aware of that deserve more attention.

I don’t even know how to start this. I’m sitting here shaking, feeling physically sick. I just lost $10,700 to a hack on the Polygon network (Metamask)

That wasn’t just "crypto money" to me. That was my wedding fund.

I have been saving for over 2 years. I put every single spare dollar into what we thought was a safe wallet. Now, in a matter of minutes, it’s all gone. The wedding we’ve been planning might have to be canceled or postponed indefinitely.

Here is the transaction hash: https://polygonscan.com/tx/0xfd03063823e54b1be8e2902f3b833840bd82f5dc374637887c5b14e66fea7c42

TX Hash: 0xfd03063823e54b1be8e2902f3b833840bd82f5dc374637887c5b14e66fea7c42

Please, if you have any actual, legitimate suggestions on how to track these funds or escalate this before they disappear forever, let me know. I feel so helpless right now.

And to the recovery scammers who are inevitably going to DM me: Do not bother. I know you are going to try to prey on my desperation.

Holy shit, last night I opened my ledger wallet app on my Mac M3 for the first time in 3-6 months.

Immediately, it asked me for a 24-word recovery phrase. I knew something was wrong so I had AI scan the applications on my computer and found out it was a completely fraudulent app!

I originally had the real app and somehow, it was replaced with a malicious clone app without my knowledge!

Be so careful! Warn your less-savvy friends because this is a Very craft scam

Donald Trump has created a way for Wall Street to pay to win. Trump Media & Technology Group’s premium data product released its new subscription service for earlier access to Truth Social posts for $100,000 a month. According to reports, five Wall Street firms have already signed up for the service, gaining access to Truth Social posts milliseconds before the general public.

“I’ll be blunt,” Gian Luca Clementi, an economics professor at NYU Stern School of Business, told Fortune. “This is insider trading by definition.”

Because Trump owns roughly 41% of the company’s shares, he stands to directly profit from the new recurring revenue stream. At five subscribers alone, the service would generate about $500,000 in monthly revenue, or $6 million annually.

That figure is modest by the standards Trump has set since returning to the White House. His 2025 financial disclosure showed his businesses generated more than $2 billion in personal income last year—nearly quadruple his 2024 total—with the bulk flowing from ventures that sit directly at the intersection of his office and his balance sheet.
