Now about the withdrawals... I wish the approval process would be a lot quicker

It's quite fast actually. I thought they would process my withdrawal "within 24 hours" as stated, however actually they did it within 1-2 hours. Moreover, with a small "economy" fee, my transaction was confirmed within 64 minutes.

It is good to know that even if they are using small fee per byte based on your transaction posted, it still went smooth. But their economy fee for withdrawal is 20k sats, so a lot of those satoshis go to their operation side? Just wondering about how they have fix tx fee and where it goes?
20,000 Sat is a very reasonable fee and it is very less when i compare it with other sites. Most sites charge 50K as withdrawal charges. 0.0002 btc equals to 2$. It may be high in terms in term of usd but we do not need to withdraw the amount on daily basis and use withdrawal only when we need money for some purpose other than gambling.
You could have idiots who will do like 1k satoshi withdrawal fee and will wait for days and they will complain about how their transaction was very slow, that is the risk these places take when putting on manual withdrawal process.
You can have maybe 3 option styles and that would be easier, my metamask has that for example and even though its always fast because it is erc20 token after all not bitcoin it still uses that 3 option system, fast/normal/slow and they put up signs like "fast takes about 1-10 minutes", or "normal takes 10-30 minutes" or "slow takes 1-4 hours" and such so when a person is doing any sort of transaction there they know how long they should wait. That three option is the max amount of power you can give to the people without them actually doing something stupid.
its possible to have a 1k or lower withdrawal fees but this wont mean that the transaction will process for a day or two . on some sites that i play they only have about 0.00004 sats fee and sometimes lower than this if the value of bitcoin is not really that high . it will then take 1 to two hours and longest will be 4 to 5 hours if the btc network is really congested or have a verry high traffic . anyway , the 20k sats that mintdice currently have is still okay as long as the transaction will process quickly maybe less than 30 minutes .
