Guys i'm still waiting for additional money but i wonder if i can do transaction now with change i've got, and then (if it dosen't get confirmed) do a rbf with that new transactions when satoshis arrives. I see i can check that rbf box for new tx, but not sure if my thinking is right while doing cpfp. Or if these two operations work separatly and cpfp wont affect rbf in the future?
Other option is to do cpfp and leave 1 satoshi from that change, and do another cpfp when i get additional resources.
I don't like second option because it would add additional bytes to my tx, so i think if i would choose 2nd option i would rather wait for my satoshis.
But never done rbf, its just changing the fee or is there any catch to it? Does it change weight of the tx or am i thinking right to try confirm with light tx and then add via rbf if it doesn't confirm?
