If they pay you with a small fee you can do a CPFP so it shouldn't be a problem because anytime you can make a transaction with the unconfirmed transaction and add an extra fee but to make sure it would confirm check it first on the blockchain explorer if it's not a series of unconfirmed transaction because if it's a series of unconfirmed transaction even you do CPFP with high fee there still a possibility the transaction will be rejected.
Or you can just wait until the receive transaction is confirmed before you spend since Electrum has coin control it shouldn't be a problem if you want to spend only confirmed transactions.
Thank you for the idea.
So you think I should put a tick next to ^ spend only confirmed coins ^ this will stop electrum trying to send out any unconfirmed low tx fee coins I will eventually receive? I dont need to use these and prefer to let them confirm before spending them. I don't want to mix them in the send with my confirmed coins.
You touch on an interesting point with coin control in electrum.
I have noticed that I set up a watch only wallet with electrum using only the import a single public address way.
This way it always sends my change to the same address that im sending from.
However. For some strange reason. If I am only spending a tiny amount of btc. Electrum wants to use every single input to that address.
This is unexplainable to me because each input uxto has enough alone for the small spend. Why would it do this?
Why would electrum choose to use every single input when 1 alone would suffice?
I noticed another guy asked this and when I checked it is happening to me also.
I am paying huge fees for very large tx size when I'm sure if I use coin control I can select to use just 1 input uxto. Not 20 inputs.
Is there a danger of doing this using a watch only wallet that spends the change to the same sending address?
I have not meddled with coin control before. Are there things to be wary of?
Thanks for any insight.
