Is this because you send the transaction with a 0 fee payable and then confirm it ourselves with the next block we find, unless someone else adds it to their block and makes no fee from it?
Well for a while this year most of the time I send it with a 42,000 sat fee so you should see it unconfirmed.
The catch is that if blocks are full, then other pools wont confirm it, if it has a fee or not, since it's a large transaction.
If no one else confirms it before our next block, then our next block will confirm it.
Can someone clarify the fees? If someone confirms the payment before the next block, will it still be 0 fee? And if it does go through with our next block, is that truly 0 fee? I am new to all this and didn't know there are tricks to getting payments confirmed with 0 fees.
