if you have delay on confirm, then i think the fee is lower than the others. i think its normally when we have got delay until 12 hours. i have experience in 24 hours without confirming, but at least i receive my bitcoin with safe into my wallet.
That's nonsense. There is no normal delay for Bitcoin. The only acceptable delay is under 1 hour (sometimes there are periods in which there is no block for quote some time). You are improperly using Bitcoin or extremely cheap and do not need quick transactions.
so maybe we need to wait and just positive thinking that traffic of the transaction is heavy than we know.
It doesn't matter what the actual transaction volume is since there are people (with money) who can and who are actively spamming the network.
Such transaction delay happens only at very rare instance.
No. It will most likely always happen if you don't adjust your fees accordingly.
thats what i thought.. is there anyway that these type of sites have a builtin calculator to calculate how much the fee should be or theres no way to detect exact transaction fee?
A lot of services are already doing it, I don't see how it'll be hard.
One just needs two numbers, recommended fee in
satoshis/byte and the size of their transaction. I'd say it's a fairly simple calculation.
