That's a transaction a customer sent to me - it wasn't me that sent it.

I know the 100-per-hour transaction limit of ViaBTC fills up very quickly - I have tried like 10 times already, ALWAYS on the hour, ALWAYS in the very first second of a new hour ( I have made sure my clock is synced properly ) and I literally watch the clock hit the 12 mark and press "Accelerate" - always getting the "Submissions are beyond limit" bullshit.

Never had that happen before, and I've used them numerous times. Yes, if I am like 5 seconds late, it's already filled, but that's normal, I guess.
