to my knowledge when first using HitBtc, every transaction is subject to a very cheap fee. and I use it for quite a long time having experienced a delay when WD because when viewed from the description because the fees used are too cheap so the transaction depends on long enough.

if at this time HitBtc make changes maybe because it does not want to be delayed by every transaction that occurs.
It is normal if for a cheap fee, you will get facilities that are certainly adjusted and things that are not reasonable if you demand excessive.
if for the purpose of repairing it is legitimate and the important thing is that every transaction can be completed quickly and we can get it.

no one wants to wait for every transaction and see the transaction delay.
