1  Local / Anfänger und Hilfe / Wo in Coinbase App angeben wieviel Gebühren man für die BTC Überweisung bietet? on: August 10, 2023, 08:49:16 AM
Soviel ich weiss kann man ja bei jeder Überweisung von Bitcoins angeben wieviel Gebühren man bereit ist zu bezahlen.

Je weniger Gebühren man bietet desto länger dauert es bis die Transaktion ausgeführt wird.

Wo GENAU (!) kann man in der Coinbase App angeben wieviel Euro (z.B. 0,10 Euro) oder BTCs man bezahlen will (für die nächste Transaktion)?

Wie lange dauert das im Durchschnitt bei 10 Eurocent?

 
2  Bitcoin / Electrum / How to find out the last EUR conversion rate update? on: July 24, 2023, 06:34:10 PM
Electrum automatically converts all bitcoins in my wallet to corresponding EUR value in a separate column.
Sometimes I suspect that the conversion rate seems not the most recent one.

How can I find out the last EUR-BTC rate update date+time?
From which server/source is the rate retrieved?

Where can I find the (virtual) EUR sum of all my BitCoins?
Read the sum of a all filled 7 addresses

3  Bitcoin / Electrum / All green addresses are suitable for receiving BitCoins? on: July 24, 2023, 06:30:56 PM
Just to Clarify:

Assume I plan to receive Bitcoins from a partner.
When I go in Electrum to tab "Adresses" then I can select arbitrarily one of the green colored 34 char long addresses
(and tell it to the BitCoin sender).

I need not to take the topmost.

And there is no hidden (auto-)refresh of the available green addresses. All green addresses are hard linked to my wallet
and stay alive until I use them.

Correct?

4  Bitcoin / Electrum / Internal algorithm how Electrum auto-selects addresses to spend money from? on: December 16, 2021, 10:10:20 AM
Assume I want to send BTCs to someone else.

On the "Adresses" tab I have multiple yellow addresses containing BTCs.
Furthermore I don't use the right click context menu "Spend from" to manually select the addresses
which should be used for the next transaction.

So Electrum will automatically choose the addresses.

How does this auto-selection algorithm work?

I can think of

1.) Select addresses with the biggest BTC amount first
     =minimize the number of used addresses

2.) Same as 1. but more smarter:
     Select addresses with the biggest BTC amount first
     but try to minimize change too

3.) Try to consilidate as much addresses
     = minimize the number of addresses in wallet which contain BTCs afterwards

4.) Minimize fee by selecting addresses with minimum number of previous Inputs

5.) .....?

Sample addresses:

11....11   0.06 BTC
22....22   0.05 BTC
33....33   0.03 BTC
44....44   0.02 BTC
55....55   0.01.BTC

BTCs to transfer: 0.09 BTC

Resulting used addresses for algorithms:

1.) 11.....11 + 22...22
2.) 11.....11 + 33...33
3.) 22.....22 + 33....33 + 44....44 + 55....55

Which algorithm is implemented?

Can I select algorithm?

Is the algorithm Electrum specific or defined for all BTC wallet software?
5  Bitcoin / Bitcoin Technical Support / Search statistics about necessary transaction fees within the next x blocks? on: December 12, 2021, 08:55:35 AM
In order to better estimate the necessary transactions fees when sending BC I am searching for backward statistics over the last month resp resp last year.

How much BC/sat do users had to spent to get a transaction executed within the next x Blocks?

Is there somewhere a statistic chart showing this for the last months?

Thank you
6  Bitcoin / Electrum / How to select BitCoin address for receiving money? on: November 14, 2021, 10:33:03 AM
Sorry for this newbie questions but I need some help.

I setup Electrum in the past and it runs fine with some BitCoins on some addresses.

Now I would like to get some more BTCs from another person.

How do I select the Bitcoin address to which the partner should send the BTCs?

On tab "Addresses" there are approx 30 empty green addresses with "receiving" type status and 10 more yellow addresses with "change" type status.
Two of the "change" addresses contain already Bitcoins.

Is it recommended to get more Bitcoins on addresses which contain already Bitcoins?
If it is better to select empty addresses: Should I use empty green "receiving" or empty yellow "change" addresses for it?

Whats the difference at all?

Thank you
Peter
7  Bitcoin / Electrum / "unconfirmed"=pending in mempool or Added to Block+waiting for 3 more blocks? on: June 07, 2018, 03:30:08 PM
What does "unconfirmed" (in Electrum) mean as label for transactions?

Does it mean:
1) Transaction is succesffully added to Mempool
or
2.) Transaction is successfully added to block and waiting for 3 (or 6) more blocks to be really seen as stable/confirmed?

8  Bitcoin / Electrum / Electrum "description" field when sending BTCs for internal use only? on: June 07, 2018, 03:54:39 AM
When I send BTCs to another address and enter something into the "Description" entry field in "Send" tab: is this text send as well to the recipient or for internal use only?

In case it is accompanying the transfer: Every letter counts as one byte regarding the fee. Correct?

In case it is for internal use only: Is there another way to pass some small additional info text ?

9  Local / Anfänger und Hilfe / Suche einfachen SEPA/Paypal-to-Bitcoin Tausch Service on: June 06, 2018, 06:09:33 AM
Ich suche einen einfachen Online-Service für kleinere Beträge (100 bis 300 Euro) bei denen ich dem Service per SEPA-Überweisung oder per Paypal oder Kreditkarte den Betrag in Euro schicke und die mir den Gegenwert in Bitcoin überweisen.

Ich will aber keine umständliche Registrierung mit Identifikation und Videoaufnahmen und Formularen ausfüllen müssen.

Dem Geldwäschegesetz sollte es genügen wenn ich durch die SEPA-Überweisung oder das sendende Papyal-Konto identifizierbar bin.

Früher gab es ja ein paar solcher Services wie etwa

btcdirect.eu

oder

anycoindirect.eu

Die haben aber inzwischen auch diese nervige langatmige Identifikationsprozedur eingeführt.

Aber vielleicht kennt hier jemand noch einen anderen Service bei dem das einfacher geht.

Vielleicht ausserhalb der EU?

Danke

10  Local / Anfänger und Hilfe / Wie nachsehen im Mining-Pool über die Existenz einer Transaktion? on: June 04, 2018, 05:02:48 AM
Angenommen A veranlasst eine BitCoin Überweisung an die (vereinfachte) Adresse  445566, die jedoch wg. niedriger Gebühren nicht zeitnah ausgeführt wird.

Kann ich auf einer (welcher ?) Webseite nachsehen, ob diese Transaktion erfolgreich im MiningPool angekommen ist?

Und wenn ja mit welcher angebotenen Fee?

11  Bitcoin / Electrum / "Replace-by-Fee": How to increase fee from Electrum? on: June 04, 2018, 03:26:05 AM
When I send BTCs to another address the "Replace-by-fee" flag is automatically set.
Thats fine.

Question in advance:
Is there a way to let me estimate how long the currently pending transaction will most probably need to be executed?
I can imagine that there is a webpages which shows this information.

Now lets assume the time is much too long and I want to replace the previously offered fee by a higher fee.

How do I achieve this in detail?

Should I simply re-enter and re-send the previous transcation this time with a higher fee?
Or do I need a transaction reference number?
Or do I have to set somewhere a flag "This is a replace-fee transaction"?

Most important: How does the Mining pool identify the replacement?
Its not that simple as it seems to be at a first glance.

Assume the original transaction looks like (addresses are shortened for simplicity):

send 0.001 BTC from 665577 to 123456 with 0.0000002 BTC offered fee

Now when I re-enter in "send" tab the same target address then Electrum  could automatically select another senders address.
The user has hardly any chance to enter the original senders address since Electrum AUTOMATICALLY select it.
Now let say Electrum randomly selects as senders address this time 442211 and generates the following transaction

send 0.001 BTC from 44221 to 123456 with 0.00005 BTC offered fee

How does the mining pool know that this is a fee replacement transaction?

Thank you
Peter



12  Bitcoin / Electrum / How to tell Electrum from which address(es) to send Bitcoins? on: June 03, 2018, 10:09:39 AM
Assume I hold Bitcoins on multiple addresses managed by my local Electrum wallet.
Simplified example with shortened addresses:

address:        amount:
556677         0.0000410
334422         0.0000500
229977         0.0000700

Now I want to send an amount of 0.0000600 Bitcoin (plus fees) to someone else.

How do I tell Electrum from which of my addresses the amount (resp.how much) should be taken?

How do I tell Eletrum from which of my addresses the (currently unknown) fees should be taken?

The "send" tab does not provide a "take xxx from local address" entry field (resp.fields)

How does this work?
13  Bitcoin / Electrum / Can I manage BitCoin Cash with Electrum too? on: June 02, 2018, 11:46:59 AM
As far as I know Electrum is designed for BitCoin (classic).

Is there a way to handle BitCoin Cash as well?

If yes: How do I distingish between these two cryptocurrencies?
14  Local / Anfänger und Hilfe / Anleitung um mit Electrum BTCs zu empfangen oder zu senden? on: June 01, 2018, 04:38:53 AM
Ich habe Electrum bei mir auf dem Desktop erfolgreich installiert.

Wie kann ich jetzt von einem Bekannten BitCoins empfangen (und später an ihn senden)?

Gibt es dazu eine einfache Anleitung?

Genügt die Electrum Installation um Bitcoins zu empfangen und zu verschicken?
Oder muss ich mich als Nutzer noch irgendwo im Bitcoin System anmelden oder bei einem Server registrieren?

Wie erkenne ich, ob ich (wieviel) Bitcoins erfolgreich empfangen habe?

Im "Empfangen" Tab von Electrum kann ich eine "Empfangsadresse" erkennen.

Genügt diese Information für den Sender um mir BitCoins zu schicken?

Ich will wie gesagt keine Bitcois (in Euro oder andere Cryptowährungen) tauschen sondern nur empfangen und senden.
