thank you very much Mocacinno,

you explanations and links are very helpful,
I wrote a private message to Quickseller, and also by now, that I understood a little thing,
I sent him the transactions ID's.
 Waiting for his replay and looking forwards to have my problems resolved,
and off course, also will, ASAP, change my wallet for a more efficient one.
(I am using mycelium, which does not give me the option of choose a fee or to resend it with a more proper fee.)

truly appreciate,
Lincon

thank you all for the support

Hello Everyone,

as you all may see, I am a complete newby,
I am not sure that I am posting it in the correct place,
but someone could support me with a stuck transaction?

" Have a transaction stuck since a week, it is  2.2BTC.
It was sent to me from a Blockchain to my Mycelium wallet,
it was with an automatic fee of 120sat/byte, with a total of 44.880sat.
I know that for the high demanding of transactions it is a very low fee.
for that I am willing to pay a higher fee with no problem,
but as I understood, the Blockchain sender does not have a option of resent with a higher fee,
and neither do I with Mycelium to offer a bigger fee to confirm the transaction. "

thank you all in advance for any good tip in my case,
Rodrigues
