I am not trying to defend this platform but back in the old days I have waited a week for my Bitcoin to get processed, I thought the platform have decided to scam it's customers and I've already moved on and later I got the Bitcoin, thing is this platform is too big to close down now, I advice you have some patience first, after doing all the necessary things like getting in touch with them just hold back and wait.
Yep, we all want the withdrawals to be instant, but usually that's not the case: and we need to wait a week or even two to get our funds rolling.
If the platform is credible, it's going to deliver, but it may be frustrating to wait for so long.
