What's Bitcoin Core behavior after running out of the 999 receiving and change addresses it generates when creating a wallet?

Does it starts reusing them from the beginning again? Or does it keeps generating addresses 1000, 1001, 1002, etc?
If the latter, what are the implications for when you restore from your hdseed? Do you need to take extra steps to make your wallet aware of beyond 999 addresses?
What's the Electrum behavior for this? How many addresses it generates by default?

Bitcoin Core 18.1 still does not support SegWit addresses for message signing, rendering the sign message feature useless for new wallets. Is there a reason for this?

Bitcoin Core 18.1 still does not support SegWit addresses for message signing, rendering the sign message feature useless for new wallets. Is there a reason for this?
Headline sounds passively aggressive, but I just don't get it how the Bitcoin Core Wallet still does not support this while being the main force regarding Bitcoin's development.
More than two years after the introduction Bitcoin Core still does not support the signing of messages using standard P2SH ("3"-addresses) and bench32 encoded addresses ("bc1"-addresses), which are de facto becoming the standard for transactions on the blockchain.
Unfortunately it is not possible to create old style P2PKH "Legacy" addresses with Bitcoin Core anymore; new addresses are always SegWit-compatible. This is *not* a bad thing, as it thrives SegWit adoption, however the in the title mentioned signing feature does not work with these addresses.
The sign message feature is was such a wonderful function to easily prove the ownership of funds and their address. Electrum and Trezor support the signing with the new standard btw, so is there a reason why Bitcoin Core does not?

THE FEATURE I'M TALKING ABOUT. ARGHHHHHHHHHHHHHHHHHHHHHH!

Coinpot stopped paying Auto-payments

My moonbit is not connected to my Coinpot account.
I left it that way. I got payments almost every week from my Moonbit account until 3/25 I no longer received. When I checked moon faucets, their last auto payments was 3/25.
I tried connecting my moonbit to my Coinpot account using "sending satoshi to my Coinpot Bitcoin" core wallet address. Sent 0.0005. Later I found out that the minimum deposit is 0.001 so I sent 0.001 to connect it. I sent a total of 0.0015 but I did not receive my satoshi to my Coinpot account and my Moonbit is still not connected.
This happened 2 weeks ago. They updated the site and added Coinpot tokens. I'm happy with the tokens but I could not get it from Moonbit because it is still not connected to Coinpot.
My moonbit account has 100+ referrals and 100 daily loyalty bonus. I am still collecting satoshi without knowing if I will still get my payment.
I tried e-mailing them but I know that I will not receive an answer.

Finding my BCH in a Bitcoin Core wallet

I decided to dig up my BCH this morning: * created a new bitcoin core wallet and transfered my BTC there. * Downloaded electroncash wallet software and put it in a Docker sandbox * Found instructions on how to ask elecroncash to "sweep" the bitchcoin from a BTC address * Found instruction on how to get my bitcoin core wallet addresses, and private keys for them.
Here is where my confusion starts. Using getaccountaddress "" and getaddressesbyaccount "" I assumed that was the full list of addresses in my wallet.
None of these addresses had any BCH. Yet, I know I had some BTC in this wallet at the time of the fork. So im concerned at this point. I keep digging.
Back in my original bitcoin core wallet, under the transactions tab, I find the transactions that received BTC prior to Aug 1. WTF? There are recv addresses that are not listed in getaddressesbyaccount "", and (yay) they have my BCH.
Im also confused because about half of the addresses printed by getaddressesbyaccount "" fail to give me a private key via dumpprivkey. They just say: Private key for address xxx is not known (code -4)
I did find my BCH, but its all very confusing. If somebody is willing to take the time to explain the bitcoin core wallet address confusion I would appreciate it.

Bitcoin Core problems

Hey thanks for reading, I'm new to bitcoin (and Reddit!) and having some issues.
I successfully bought some bitcoins and had them transferred to my Bitcoin Core wallet address, only I didn't realise that I needed to be fully synced before I would see them.
I've been having some issues with the computer that I had Bitcoin Core installed on and it keeps restarting every now and then, which causes Bitcoin Core to display the "No block source" message forcing me to reindex. This takes forever to do and so I've installed Bitcoin Core onto my laptop and started downloading the blockchain there with no problems so far.
My question is, once I've got it fully installed onto my laptop will I be able to transfer the blockchain files from the laptop onto my computer so that I can access my bitcoins? Is there an easier way to access my bitcoins if I know the address they were sent to?

Kraken: We won't support native Segwit Bech32 addresses until there is "full support in wallets such as bitcoin core"

https://twitter.com/krakensupport/status/949596199006306304
When confronted about not supporting Segwit fully, exchanges are starting to point the finger at bitcoin core's slow implementation in areas such as change address management, bech32 native sending or full native wallet generation.
Segwit would be adopted much faster if this basic support was in the seminal node implementation. Just sayin.

Bitcoin Core Wallet (Version .0.15.0.1) To Ledger Nano S. Should I Use “Legacy” or “Segwit” Address Type?

I currently have Bitcoin on the Bitcoin Core wallet Version 0.15.0.1. I am looking to send that Bitcoin to my Ledger Nano S. However, when I open the Ledger Wallet Bitcoin app in Chrome and unlock my ledger, I obviously select “Bitcoin”, but the next screen asks for the address type…either “Legacy” or “Segwit”. I am looking for someone to confirm what address type I need to select, or if it even matters. If it does matter, can someone explain why I would send to one and not the other and/or visa-versa?
Once this Bitcoin has been transferred, I have a very small amount of Bitcoin on an exchange and I would like to send that to my Ledger Nano S as well. Do I have to be concerned which address type to send to from the exchange?
Thanks for your help in advance.

[Question] When I send using Bitcoin Core wallet, is the wallet managing the "never use the same address to send more than once" guideline?

I understand that if one has a paper wallet (a single address), that it can safely receive limitlessly. However, you should only send once with it. If I am using Bitcoin Core wallet, is this concern being handled automatically?

Redownloading bitcoin core wallet on desktop. Will I be able to retrieve bitcoin sent to wallet address a year ago?

I bought about $90 worth of bitcoin about a year ago via coinbase, and sent it to my bitcoin core wallet. I was fairly inexperienced at the time and sent the amount before the block chain had finished syncing. It took so long that my computer started to run out of disk space so I deleted the wallet and forgot about it. Recently re downloaded bitcoin core and am currently syncing. What are the changes that I ever get my bitcoin back??

Restoring wallet address (and funds) to Bitcoin Core

Hi all,
In an effort to send my BTC from Coinbase to a wallet, I downloaded Bitcoin Core and sent funds from my Coinbase account to my BTC Core wallet before the blockchain had synced. I let the blockchain sync for a few days but became frustrated with the time it was taking-- I cleared the directory and let the application start up again. The blockchain is downloading again, but the wallet address is different now-- did I effectively lose the BTC I transferred a few days ago? If not, how do I go about retrieving them?
Any help would be greatly appreciated.

[Question] I use Bitcoin Core. Is it poor practice to create a new receiving address to receive all unspent funds from another address (in the same wallet) that is associated with a transaction?

I understand that if a bitcoin address is used to send funds, then its public key is disclosed and it is best practice to zero it out. Short of creating a new wallet, I am thinking about creating a new receiving address in the same bitcoin core wallet and send the unspent bitcoin to the new address.
Is this good practice, or am I doing something really silly?
From a privacy perspective, I get that idealy you want an address to receive exactly once, and send exactly once to minimize the ability of analysis to connect the dots between 'businesses' and 'customers'.
From a security perspective, I believe, an address' public key is only exposed when it is used to send. It can receive limitlessly and its public key is not exposed.

Why does the wallet that comes with bitcoin core have non-Segwit addresses?

Just wondering. I am using Bitcoin Core version v0.15.1.0-g7b57bc998f (64-bit) for linux.
