Currently the only available wallet seems to be Paytaca I am hoping someone takes the lead and updates Badger Wallet.
I wish I had the capabilities to do so but unfortunately I do not.
I got some dust in an old wallet I had, but fees looks really high. Is there a way to send those Satoshis without paying a lot in fees?
I’m trying to learn about multisig. Do you ever worry you won’t have access to that location or person to be able to use your bitcoin when needed? What if you needed to flee the country all of a sudden to a bitcoin friendly country or what if the other person isn’t available? Is this a risk with multisig?
Imagine if you combined the speed of The Internet, the convenience of PayPal and and the economic power of Gold into one global economic system, where:
This is The Future of Money.
This is Bitcoin.
Where to buy and store? I have bought some crap coins on Revolut before but I am paranoid if they go bankrupt etc.
Can someone explain to me in very simple terms what is the difference between Bytes and Virtual Bytes on BTC chain, cause as I understand BCH only messures in Bytes sats/Byte, I looked it up but was complex to understand for me, the only thing I uderstood was that it works on SegWit so Bitcoin Cash dont has this

Txns now say 'unknown Transaction'. About 1 bch is missing total. [link] [comments] |
First some basics for Ledger:
Secure Element:
The secure element is not an unbreachable storage chip, it is in fact a little computer. This computer is secured in a way that it enabled confidential computing. This means that no physical outside attack can read thing like the memory on the device. The secure element is and has always been a defense against physical attacks. This is what makes Ledger a better option than let's say Trezor in that regard, where you can retrieve the seed just by having physical access to the device.
Phygital defense
Ledger uses a 2e STmicro chip that is in charge of communicating with the buttons, USB, and screen. This co-processor adds a physical and software barrier between the "outside" and the device. This small chip then sends and retrieves commands to and from the secure element.
OS and Apps
Contrary to what most people believe, the OS and apps run in the secure element. Again that chip is meant to defeat physical attacks. when Ledger updates the OS, or you update an app, the secure element gets modified. With the right permissions an app can access the seed. This has always been the case. Security of the entire system relies on software barriers that ledger controls in their closed source OS, and the level of auditing apps receive. This is also why firmware could always have theoretically turned the ledger into a device that can do anything, including exposing your seed phrase. The key is and has always been trust in ledger and it's software.
What changed
Fundamentally nothing has changed with the ledger hardware or software. The capabilities describes above have always been a fact and developers for ledger knew all this, it was not a secret. What has changed is that the ledger developers have decided to add a feature and take advantage of the flexibility their little computer provides, and people finally started to understand the product they purchased and trust factor involved.
What we learned
People do not understand hardware wallets. Even today people are buying alternatives that have the exact same flaws and possibility of rogue firmware uploads.
Open source is somewhat of a solution, but only in 2 cases 1. you can read and check the software that gets published, compile the software and use that. 2. you wait 6 months and hope someone else has checked things out before clicking on update.
The best of the shelve solutions are air-gapped as they minimize exposure. Devices like Coldcard never touch your computer or any digital device. the key on those devices can still be exported and future firmware updates, that you apply without thinking could still introduce malicious code and expose your seed theoretically.
In the end the truth is that it is all about trust. Who do you trust? How do you verify that trust? The reality is people do not verify. Buy a wallet from people that you can trust, go airgap if possible, do not update the firmware unless well checked and give it a few months.
Useful links:
I want to get away from using third-party wallets, even hardware, and truly self-custody in the simplest way possible. I'm not a dev nor do I have experience running a node. I understand that a paper wallet is self-custodying my own public and private keys, but I'm confused how I get there.
For example:
Say I buy BTC on Coinbase.
At this point, it's in Coinbase's custody, so I obviously need to withdraw it [somewhere?] to self-custody it.
Where would I send my BTC to?
Before bitcoin was invented all these people had to do research to pick and choose which stock to put their money in. Now, it's a no-brainer that bitcoin is the best place to put your money. No more need to delegate hours of your life to research any investing strategies or this or that or which stock is best or when to buy or when to sell. The answer is to just always buy bitcoin.
I'm a junior programmer, and I'd like to get into Bitcoin Cash development.
One thing I would like to do is build my own full node from scratch, to learn all the parts involved in depth.
I have read Mastering Bitcoin Cash (adapted from Antonopolous'), but I'd like to know if there is a programmer tutorial to implement a full node.
Even if it is a simple UTXO-based node that's cool.
Thank you!

This Udi guy won't deny that Craig Wright is paying him to spam BRC-20 transactions?
Rust: Bitcoin Wallet on playstore is a scam wallet. funds were taken a few hours after depositing and are already being shuffled through multiple wallets.
Im thinking of using bisq and moneygram. I just want to trade usd for btc without anyone knowing about it. Has anyone done this? Are there better methods to do this?
Thank you.
In the future, Do you guys think war will be fought because of Bitcoin or Crypto in general?
I want to to speed up 2 transactions : one is worth $25 (11 days old) and one is worth $7 (2 days old)
Those transactions weren't sent by myself.
Is there a way to speed them up to get confirmation?
To the person who ripped the bitcoin bumper sticker off my car. I just bought 2 more.

Mempool fees dropping while transaction volume is high tells me the people who waited for confirmations are coming to the front of the line. Was interesting, but I expect without another dump of high fee payers we are seeing the start of the end of the backlog. [link] [comments] |
