This works.
Thank you

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?

 

Thank you.

But where do I change these values?
I am using the portable version of Electrum

Electrum automatically converts all bitcoins in my wallet to EUR.
Sometimes I suspect that the conversion rate seems not the most recent one.

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

Peter

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?

Peter

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

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?

Thank you for comments

As I learned (even from this forum) no one should send BTCs to the same address more than one time.
So how can it happen that there is more than 1 input per address?

The only situation I can think of is when it took place accidentally or by inexperience.
So normally (in 99%) all send addresses count as 1 input.

Am I correct?

Ok, thank you very much for the helpful comments.

One more question about calculating the necessary vBytes.

Just to clarify what I read and understand so far from other webpages:

If I want to send BTCs from my Wallet (in Legacy Mode) and
I send BTCs from x own addresses to y partner addresses and get back the change on 1 more own address I will have to pay for

x * 149 + y * 34 + 1 * 149 +-10 =  .... vBytes

Correct?

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

Thank you so far for the helpful comments.

Just to clarify the procedure:

I receive BC:

1.) I pick one of the green empty addresses from the "Addresses" tab and tell it the BC sender together with the BC amount e.g. 0.03 BC
2.) I will receive automatically the full BC amount and as soon as it is written to blockchain it appears automatically in my "Addresses" Tab as yellow line

correct?

1 want to send BC:

1.) I got from the recipient his BC address
2.) I go to "Send" tab and enter the address from 1.) over there in "Pay to" entry field together with a description and the amount and click button "Pay"
3.) The BCs are AUTOMATICALLY taken from one or more of my yellow, non-empty addresses. A part is sent the the recipient. The remaining change is pushed back to another of my yellow, empty addresses

Questions:

Do I have any control from which of my yellow, non-empty addresses the send BC amount is taken?

How do I specify how much I am willing to pay to the miner as transaction fee?

Thank you so far for the comments.

So I should receive BCs on empty addresses only. Ok

But why are there yellow AND green empty bitcoin addresses?

As far as I understand if I send some 0.02 BC from an address in my Electrum Wallet containing 0.05 BC then Electrum
- sends 0.02 to the given target address of the recipient
- creates automatically a new empty address
- send the remaining change of 0.03 BC to this new address
- add the new, just created address automatically to the list of yellow change addresses visible on the "Adresses" tab.

So why are there empty yellow addresses listed on "Addresses" Tab?

Peter

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

So this "testnet" is not really a network or a special BlockChain view.

Is is just a special BlockChain server.

The Sender has manually to add the MetaData and Receiver has manually to check this special server for reading the MetaData.

If the receiver does not know that the sender has added something then he will never read it.

Correct?

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?

@HCP:

Ok, thank you.
Regarding Option 1:

What is the internal strategy of Electrum for selecting the addresses?
I can think of:

- oldest first
- try to minimize the number of local addresses
- try to pay with using a minimum of addresses
- random pick of addresses until amount is filled.

Can users tell Electrum which strategy to use?

Is the default strategy for other Wallets the same?

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 ?

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

Peter

Also wenn ich unter dem angegebenen Link oben rechts die Zieladresse eingebe werden mir nur die bereits durchgeführten Transaktionen angezeigt.

Ich will aber den Stand der wartenden Transaktion im Mining Pool sehen.

Also ob die Transaktion überhaupt erfolgreich in den Mining Pool aufgenommen wurde.

Das geht mit [Suspicious link removed] NICHT

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?

Peter
