well I'm trying viaBTC to accelerate my transaction but I'm getting error message Submissions are beyond limit. Please try later.
I'm having the same exact problem with one transaction thats taken 25 hours now.
The counter resets every hour like 1.00, 2.00 etc. So try accelerating it when a hour switches and it will succeed with much higher rate.
I got acceleration succeeded when I just did it on the hour. Still says unconfirmed, how long does it normally take?
