This is the second time I used this specific Exchange that doesn't have dynamic withdraw fee and their transactions often take 4~12 hours. Do you guys know somewhere where I can get this kind of service? Already tried viabtc.com but they are overloaded which requests.

And also, this fee is way too low, right? https://live.blockcypher.com/btc/tx/b08a8f63aebe6f479032835604fc3eaecf17376b31a218b26cd224ceecf41930/

I probably should open ticket to let them know how shitty their services are...
