Has anybody tried to send a zero fee transaction? I might have a go if nobody has attempted it.
I don't see the point of attempt broadcast transaction with 0 fees since we know most full nodes & server for SPV wallet won't relay it, unless you managed to connect to nodes owned by pool which accept transaction with 0 fees.
But there's no harm doing that, so you can try it even though we can guess the result.
So does this mean that it is still possible? If there is a pool of miners who accepts it?
I think we can try because we can set a new tx fee for an already broadcasted transaction anyway.
