Also, 100% fee multiplier is good enough for fast confirmation (less than 2 hours)?
You can check a site like http://bitcoinfees.21.co to see what recommended fees are for fast confirmation. For example, right now the fastest and cheapest transaction fee is currently 160 satoshis/byte!
Using the dynamic fees feature, you can simply slide the bar to the far right to get a quick confirmation and you won't have to worry about figuring out the correct fee to use at the current time.
I'll do that, i don't want any fee bug anymore.
this feature does not exist anymore in recent versions.
recent versions have dynamic fees, and they display the expected confirmation time of your transaction depending on how much fee you pay.
I didn't realize i use outdated version, thanks for the info.
