Well, I am sort of in need of exactly such list and while it is a bit outdated - does anyone know if there is anything similar but with most updated information?
2  Local / Anfänger und Hilfe / Cryptofreundliche Banken in Österreich on: August 10, 2020, 11:40:19 AM
Hey Leute,

Situation:
Ich wohne nicht zur Zeit in Österreich werde aber bald ein neues Unternehmen in Österreich gründen (GmbH) und deswegen brauche ich ein Geschäftskonto. Für meine Services und Dienstelistungen werde ich auch Crypto als Zahlungsmittel akzeptieren und ich weiss nicht zu welcher Bank ich mich wenden soll. Die Bank soll auch nichts dagegen haben, habe aber gehört, dass die Banken mit solchen Firmen nicht viel zu tun haben wollen.

Transaktionsbeispiel:
- Kunde zahlt mit Cryptowährung
- Die Zahlung wird von BitPay oder CoinPayments verarbeitet und die Cryptowährung wird direkt an unsere BitPanda-Brieftasche gesendet
- Sobald sie die BitPanda-Brieftasche erreicht, wird sie sofort in EUR-Fiat umgerechnet
- BitPanda sendet eine SEPA EUR-Auszahlung auf unser Bankkonto bei unsere Bank

Frage:
Ich habe mich bei Erste Bank schon gemeldet, Businessplan gezeigt und alles, aber wenn sie erfuhren, dass es etwas mit Crypto zu tun gab, haben die abgelehnt. Und ich habe zwar gelesen Erste Bank sei cryptofreundlich. Bitte, wenn jeman schon selber Erfahrung hat oder in ähnlichen Situation war mich ein bisschen damit zu Helfen.

Frage 2:
Weiss jemand etwas mehr von der Registrierungspflicht bei der FMA?

Danke!

- I imported my seed from original Bitcoin wallet to Electrum to an offline
Has this seed / mnemonic code been generated offline?
If not, there is no reason to use it on an offline computer now.

It was initially generated offline using BitcoinCore, then the private key was imported to Electrum offline.


What exactly did you import into electrum?

A single private key for a single address?
A master private key for all addresses?
Or a mnemonic code (12/24 words) for all addresses?

If the sensitive data has been created offline, you are definitely fine to regard that as a cold wallet.
But what bothers me is that you might have not used the original core since it does not provide you a mnemonic code.

Can you verify that you imported the master private key (starting with xprv.. yprv.. or zprv..) ?

Hello,

Thanks for all the responses. The community here is great indeed.
As I am not a frequent crypto user I expressed myself wrong because I do not make a big difference between seed and private keys.

What I exported from BitcoinCore and imported into Electrum were the private keys, not the seed words.
I have also verified the executable files with signature so I am pretty sure I am using the original software.

Thanks for all the warnings though, as I already said - great community here and cheers.

Hey guys,

I finally decided to give Electrum a try. My setup is as follows:

 - I imported my seed from original Bitcoin wallet to Electrum to an offline computer
 - I installed Electrum on an online computer and there I created a watch only wallet with the master public key I exported from the offline computer

When I want to create a transaction from the online computer, save it to USB and sign it on the offline computer  I do not see anywhere a PREVIEW button as it is described in the Electrum documentation. See the images below:





Can someone guide me step by step how to do it in the new version?
