Bitcoin Transaktionen kosten im Moment im Durchschnitt ca. 18 Dollar. Man kann ja die Gebühr selbst festlegen und damit die Geschwindigkeit der Überweisung steuern. Wählt man zuwenig, wird sie evl. auch nach Tagen nicht ausgeführt. Evl. reicht aber auch eine kleinere Gebühr, wenn die Transaktion nicht in den nächsten Block der Blockchain kommen muss und man evl. Zeit für ein paar Tage hat. Dann reichen evl. schon wie unten zu sehen 4 Satoshi per Byte.
Bei BTC hängen ja die Gebühren nicht an dem Betrag, sondern an der Länge der Transaktion, die je nach Adressentyp unterschiedlich ist.
Man kann hier schauen, was so im Moment berechnet wird. Dort steht:

The fastest and cheapest transaction fee is currently 102 satoshis/byte, shown in green at the top. For the median transaction size of 224 bytes, this results in a fee of 22,848 satoshis. |
Das ist aber umständlich. Um die aktuelle Kosten anzuzeigen, habe ich einen kleinen NodeRed-Flow im Dashboard entwickelt, das einen Web-Service von mempool.space abfragt und anzeigt. So sieht man auf einen Blick, welcher Betrag ca. für welche Zeit nötig ist.
So braucht man nur einmal auf den „Update“ Button klicken und erhält die Möglichen werte um nicht zuviel zu bezahlen. Manche Wallets ermöglichen ja auch nachträglich die Kosten zu erhöhen wenn die Transaktion nicht durchkommt. Das nervt zwar, spart aber und nennt sich Replace-by-Fee (RBF). Hier das Dashboard:…
