Hallo @Moeter81,

viel Erfolg bei deinem Angebot. Zur Sicherheit aller Beteiligten aber von mir einmal der Hinweis, dass der Nutzer im OP kürzlich nach langer Inaktivität aufgewacht ist und davor überwiegend im englischsprachigen Bereich aktiv war.

Und weil wir ja alle möchten, dass diese Deals hier für alle Parteien reibungslos ablaufen, erinnere ich daran, dass man bei neuen oder lange inaktiven Accounts immer besondere Vorsicht walten lassen und am besten nur mit einem Escrow handeln sollte.

Sicher ist sicher.  

So basically you have to enable developer mode to show & install the app? Or are there additional steps that you need to do before installing the app? Kinda weird they don't explain this in the official guide. Since migration is necessary for NEO holders I don't know why it needs to be gated behind a developer mode either, CMIIW. Glad to see you work it out OP.

Does the language setting have no effect? Given that the Deutsch has several enriched fonts, it is possible that it was automatically integrated into the keyboard and affects the input word. Try to use the default language whenever possible.

Good luck.

So you can't find Neo N3 and NEO app? Or is it the latter? If I understood the explanation correctly, the old app is no longer supported and you need to use the N3 one. If you still can't find it, probably contact their support for further help. I've never seen anything like this assuming everything is updated etc. I don't think it is an internet problem either, I could be wrong though. CMIIW.

Since you've mentioned that firmware and everything have been up to date. Have you seen this article from them about Neo's upgrade last year?
(https://support.ledger.com/hc/en-us/articles/115005530425-Neo-N3-NEO-?support=true)

According to you other thread, your Ledger Nano X is new.
So, have you updated its firmware yet? Because the device that you've received might have an outdated firmware.

Do you mean "Ledger Live"?
Clearing the cache should also clear the spent coins after it resynchronize.

Normally it's not much of an issue in most wallets, unless we're taking about thousands of small payouts.
Yours is a unique case.

That setting will also save you some satoshi later when you need to spend your mining rewards.
Because it could cause you to pay more fee if you end up creating transactions with high number of inputs (higher transaction size).

What is your exact model of ledger hardware wallet?
Old and retired model S is slower than newer models, but I don't think this change would speed anything in your case, and your computer hardware and processor is more than enough.
Maybe hardware wallet devices with faster processors will have less issues with many transactions, but this is just my speculation.

Did you choose any other manufacturer for hardware wallet?
I would suggest getting something that is open source, and if you are only dealing with Bitcoin than Passport by Foundation could be good option.
As for other hardware wallets, I never heard someone had problems with mining rewards, but you can check the list I made for open source wallets available today:

EDIT:
I did some research about Trezor hardware wallets, and they are saying that Trezor is not designed as a mining rewards wallet because of high  number of transactions,
so they are suggesting costumers to compile more transactions to one and then deposit to Trezor wallet.

Does it get faster once you have less remaining funded inputs in your wallet?
I also wonder if your Ledger with the current wallet will work okay again once all your inputs are consolidated, or that somehow the existence of those used addresses will still slow it down.

My assumption was this problem occurs while creating the transaction, but if you're right, it's while signing it. Is that correct, OP?

I would not use paint thinner, that dissolves all kinds of plastic.

Still, 400 inputs isn't that much, and if that would be a problem, I would have expected much more complaints about it.

That should work, as far as I know Trezor uses the same seed format. Whatever you do, don't enter your seed words in any website! You probably know this, but people still do it once in a while.

Alternative: use IanColeman's software to recover private keys, but this requires an offline setup and you should know what you're doing including offline signing. Another hardware wallet is easier and probably the safest choice.
