Played in this casino few deposits and few withdrawals without significant issue, as far as I remember this casino do manual check for all withdrawal (no instant withdrawal).
Waiting for withdrawal is annoying, no doubt about it but nothing we cant do as players except being patient while waiting for it.
It seems that this casino is managed by a team with 2-3 persons only so it may take longer time for such withdrawal review.
I cant really see how much is the withdawal requested by above user, but I dont think it is a big amount so I think it should not take more than 2x24h for reviewing.
Edit: Oh it is 2mbtc only...
Waiting for withdrawal or even waiting for any other things are always going to be annoying for those who lack in patience. To avoid this issue to occur, it would be better if these people will read the information being posted on that thing they are going to use first. They can also ask a question to the customer representative if ever some information are missing or there are no information posted at all.
No offense but manual reviews seem to be an old-school thing and it can be costly because they may need to hire more personnel to make things faster or more effective but why can't they just make things automatic like the others? And besides they are not new on this industry anymore. As long as the developer of it is good, the outcome of it is also going to be the same.
