The visual bug was probably about the 19 free transaction acceleration slots that were displayed for almost an hour and yet when one tried to enter their TX I did, an error "Submissions are beyond limit. Please try later."
Got it. Well, I always see 0 free submissions in viabtc so maybe it's really a visual bug when accessing viabtc at that time. As I said, I always see 0 free submission on their website and I haven't been able to use their free service since the day where the transaction fee increase a lot. Well, there are other free tx accelerator I used but I am not sure if it really works or not. I didn't read the last post that's why I am wrong but I wasn't going to say about it but I have seen the image and read some part of it and didn't read all of it because I am doing other important things.
