/u/btchip from the Ledger Wallet company has hated Bitcoin Cash for a long time. If you complain about the default $2-$3 fees in their software for BCH, he will attack you and accuse you of slander. TLDR: Don't buy a Ledger.

/u/btchip from Ledger Wallet company seems to admit in this comment that he does not think Bitcoin Cash has any importance. This is probably why they don't even have BCH as a default app, and allow tons of bugs to persist and blame the BCH network.

2nd Passphrase via pIN , how is that changing the private key recovery process?

u/btchip, when you use the feature with a 2nd passphrase, for example the method by a second PIN.
1) When you have such a 2nd PIN, how exactly does it work when you like to use ledger with 3rd party wallets like MEW or Metamask for example, how does the process change of coupling Ledger with the other wallet?
2) How exactly does the process of recovering your funds change, when using this tool from github? https://github.com/iancoleman/bip39
Can someone please walk me through the steps. Assume for this case we like to recover one Bitcoin Account. And one Ethereum Account, Both PINs of Ledger are known, 24 word mnemonic is also known. thx

@Ledger BTCHIP: Have you patched this CRITICAL vulnerability discovered by ZENGO: DoS attacks on Ledger Live Wallets making wallet funds PERMANENTLY unusable?

https://www.coindesk.com/researchers-expose-flaw-in-bitcoin-wallets-that-could-be-exploited-for-double-spending
Ledger u/btchip, u/fabnormal, what is going on with this incredible attack vector reported by ZENGO (see above link)? About allowing "replace by fee" RBF function by the Live Wallet.
The article states that you have only patched one of TWO CRITICAL vulnerabilities. You fixed the part "user erroneously believes a pending transaction has already been confirmed".
But this is only one - the much less dangerous - part of the vulnerability.
What about this even more dangerous SECOND ATTACK vector, also linked to the RBF function?
This second flaw is essentially a DoS attack which PERMANENTLY destroys a user's wallet address and makes spending from it impossible
When are you solving and patching this attack vector? And can you solve it? I understand you should adjust your *coin selection algorithm *
This second attack is incredible, it is a direct knockout, anyone with some knowledge can destroy any user's wallet at will. Anytime, from anywhere. No physical access needed, no spyware or hacking needed!
And the user can't do a thing about it to prevent it. How are you allowing such a huge vulnerability to exist?!
Who needs the hardware security if anyone can block you from USING your wallet?! in the end it is like stealing, in both cases you cannot spend anymore.
, Here the quote how the article describes this attack:
"Attacker artificially inflates a victim's balance by sending repeated transactions to her wallet. This can be done without a victim's consent. By rerouting the transactions before they are confirmed, the victim's stated wallet balance and actual funds are again decoupled, making their wallet unusable. Worse, the attack can affect multiple wallets at the same time."
"Essentially, it’s a denial of service (DoS) attack, preventing people from using their wallets. This also disables other kinds of sending attempts if the wallet’s coin selection algorithm chooses funds from this nonexistent transaction,”
This is an incredible vulnerability, no way to prevent. Explain to use have you solved this already, or what is the status? Or do you like to keep it that way, why?! Thanks

RBF bricking possible?

This thread (https://old.reddit.com/ledgerwallet/comments/hjypec/double_spend_possible_on_ledge) was on the RBF vulnerability. btchip linked to Ledger's website post on the matter (https://www.ledger.com/trickery-is-not-a-vulnerability). I might have missed something; but it does not seem to address the second order attack which could permanently disable a wallet with or without the victim’s knowledge of the transaction. From https://www.bit-cointalk.com/2020/07/02/researchers-expose-flaw-in-bitcoin-wallets-that-could-be-exploited-for-double-spending/ : "Essentially, it’s a denial of service (DoS) attack, preventing people from using their wallets. “This also disables other kinds of sending attempts if the wallet’s coin selection algorithm chooses funds from this nonexistent transaction,” Ohayon said. These wallets are “bricked,” to use Sutch’s parlance.
The technical details are over my old head... but the mention of "bricking" causes alarm. The post on Ledger's site states that " your crypto, recovery phrase, private keys, PIN code etc. are not at risk. ". But this is in reference to the first type of RBF vulnarability... not the second one. So is "bricking" possible?

Ledger CTO requests suggestions to fix their product. Claims BCH is ‘fundamentally broken’.

EDIT2: I have seen a few comments and posts that make me believe that there is a fairly straightforward fix that can be implemented here.
u/btchip, you said you run your own servers to handle the fee calculations. Would you be willing to either connect to an external mining node running Bitcoin Unlimited or switch one of your non mining nodes to their software? They have indicated that their rpc response has been completely overhauled. I’ve also heard that they are discussing fees in the range of 10 bytes/satoshi.
Can anyone from Bitcoin unlimited comment?
I just had a fairly robust back and forth with u/btchip regarding the ongoing issues people (myself included) have been having with the ledger fee estimator and the low fee bug in the ledger software. u/btchip asserted several times that the issue is not with the ledger software but is related to an RPC call they are using to retrieve fee estimates from a set of non-mining Bitcoin ABC nodes they run for this purpose.
In the final message of our exchange u/btchip asks for ideas on how to fix this issue so I would like to ask the BCH community (devs in particular) how this is being done in other wallets. Clearly, the mempool data shows that many fee estimations are wildly higher than what they need to be so maybe there is some truth to what u/btchip says and maybe this is affecting other wallets. Can anyone offer some insight into this element of the code? How does the bitcoin.com wallet do this same estimation? I always get a 1 or 2 satoshi/byte fee from them whereas I always see fee estimates of 50+ sat/b in the ledger software.
Is there any truth to what u/btchip says, and if so is anyone working on improving this element of any of the current bitcoin node clients? Can we point u/btchip towards a node software with a better implementation of that particular rpc call? I am not very knowledgeable in a lot of this so any help you can give to trying to resolve this would be much appreciated.
If you want to read the exchange the thread is here: https://np.reddit.com/ledgerwallet/comments/7mzodj/bch_estimator_for_ledger_chrome_app/?st=JBTLY1SK&sh=e56cdba3
EDIT: thanks everyone for the discussion and thanks especially to u/btchip for taking the time to come here and discuss. Hopefully this can be resolved quickly so we can all get back to using our peer to peer electronic cash with super low fees and fast transaction times.
