Bitcoins Mining - so geht's - CHIP

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.

what features do you want in a wallet?

Hello!
Lawrence here, cofounder of GreenAddress, a bitcoin platform that aims to make bitcoin transactions and storage easier, safer and faster.
It has been brought to my attention that this subreddit has quite some power users and that we may be able to offer some features that better cater for traders :)
Is there something specific to your trading activity (as well as normal activity) that you would like to find in a wallet?
Our api and wallets (for windows/mac/linux/android/ios/web) currently features:
We are also integrating instant confirmation with a number of exchanges (and payment processors,ATMs, etc) to allow for instant deposits and withdrawals.
Any suggestion or feature request very welcome!!
Thanks!
Lawrence

Bitcoin Core or Bitcoin Segwit2X - The OWNERS (market) will DECIDE which is the REAL Bitcoin BTC - not miners.

I believe that both coins, Bitcoin Core and Bitcoin2X should be listed on ALL exchanges. Owners of Bitcoin will then decide which Bitcoin has greater market value. The coin that ends up with the highest market valuation deserves the title "the real Bitcoin" and the ticker symbol BTC.
Miners might be political at first, but we all know that in the end, they will mine the most profitable chain. This has already been proven, time and again.
The coins can still be technically secured on both chains using nlocktime and RBF, even if there is no replay protection. Source: https://www.youtube.com/watch?v=O4hX7GLuweM
Contact your exchange and demand that they list both Bitcoin Core & Bitcoin2x. Email your wallet & demand that they split your coins safely.
The only wallet that I know of so far, that has confirmed that they will provide support for SegWit2X chain is the Ledger hardware wallet. They clearly state "if there's no replay protection added we'll force a split before transacting" Source: https://twitter.com/BTChip/status/896056752948486148
Miners have a powerful voice BUT so do the owners of Bitcoin (the market). The owners can choose which chain they prefer, & nobody can take that choice away from them. Miners will eventually mine the coin that has the highest value.
We might end up getting opt-in replay protection added to Segwit2X (btc1). Source: https://github.com/btc1/bitcoin/pull/127
Am I missing something? If you can add further information to this post, it would be helpful.

How to Split Your SegWit2X Bitcoins Safely After The Hard Fork

In November, there is going to be another Hard Fork of Bitcoin titled SegWit2X. If you play your cards right, you could end up with coins on both chains.
This Hard Fork does not come with replay protection as standard. Instead, the SegWit2X team has suggested that they will add optional replay protection:
"After much debate, Garzik has now added opt-in replay protection to btc1 on GitHub and has proposed merging it into the codebase." Source: https://www.cryptocoinsnews.com/segwit2x-dev-jeff-garzik-proposes-opt-in-replay-protection-but-critics-call-it-useless/
Assuming that your wallet can make use of this opt-in replay protection, & IF it is added by Jeff, prior to the Hard Fork, you can use the opt-in replay protection, to move your SegWit2X Bitcoins to another wallet.
Your current Bitcoins will remain on existing wallet.
Now, you can sell whichever chain of Bitcoin you want safely, without selling the Bitcoin you want to keep. Or, you can keep both.
You will off course need a wallet (or exchange) that can make use of the opt-in replay protection. Nearer the time, the best wallets should offer this service.
Email your wallet provider / exchange & demand this service, if you want to be able to split your coins safely, & profit from the upcoming Hard Fork.
The only wallet that I know of so far, that has confirmed that they will provide support for SegWit2X chain is the Ledger hardware wallet. They clearly state "if there's no replay protection added we'll force a split before transacting" Source: https://twitter.com/BTChip/status/896056752948486148
Am I right? Am I missing something? If you can add further information to this post, it would be helpful.
This post is based on my current knowledge, which is limited. I will edit & update this post, as further information comes to light. Please carry out your own research before trying to split your coins in November. Stay Safe.

How to Split Your Bitcoins BTC Safely, Post SegWit2X Hard Fork, & Get Bitcoins On BOTH Chains

The wallet provider BTC.com revealed its decision to support both sides of the chain after the fork, and has designed its own form of replay protection. This will allow users to sell coins on either chain, safely, without it being replayed on the chain that they want to keep.

The only hardware wallet that I know of so far, that has confirmed that they will provide support for SegWit2X chain is the Ledger hardware wallet. They clearly state "if there's no replay protection added we'll force a split before transacting"

Ledger did support Bitcoin Cash immediately after the Hard Fork, & offered an EXCELLENT clean "split" option (so that you could move your BCH to an address different from your BTC address).
Which Exchanges will Help You Split Your Coins Safely?
Bitfinex: original incumbent chain is “BTC”, SegWit2x chain is “B2X”
HitBTC: original chain is “BTC”, SegWit2x chain is “B2X”
CEX.IO: original chain is “BTC”, SegWit2x chain is “B2X”
COINBASE: "the existing chain will be called Bitcoin and the Segwit2x fork will be called Bitcoin2x."
Coinbase still have not given Bitcoin Cash to people that are entitled to it. My advice would be to get your Bitcoins of Coinbase, and into a wallet or exchange that handled the Bitcoin Cash Hard Fork quickly, like Ledger wallet did!
Coinbase may change their mind later, about which fork gets Bitcoin name and ticker BTC, after "the forks are in a stable state." and may "consider other factors such as market cap or community support to determine stability."

Now, you can sell whichever chain of Bitcoin you want safely, without selling the Bitcoin chain you want to keep.

Ledger comment/instructions please? /u/btchip or /u/murzika

Can either of the two Ledger people on Reddit please provide us with a detailed statement on how they plan two facilitate the upcoming segwit2x fork in mid-november, furthermore would either of you fine gentlemen be able to provide a more detailed explanation on how Nano users will you be able to safely transact on bitcoin and also claim their forked segwit2x coin.
Given coinbase and Gemini have both already released statements stating that they will provide easy access to both chains after the fork I am hoping that ledger will outline their plans and provide instructions to their users on how to claim their share of the new coin safely as of right now I am fairly confused I understand that keeping my Bitcoin on The Ledger Nano s will guarantee that I get segwit 2X however that's also the case with the online exchanges and they are making it very simple to cash out so I am torn between leaving my funds on my ledger Nano s or moving them over to coinbase for example for ease of access....
Please advise! I am a relatively new Ledger Nano s user My breath of experience with the product is limited and I could really use some guidance on how I will go about accessing both chains post Fork so I can make a determination on which coin to sell in which to keep
Calling btchip and murzika
