I have no idea about the withdrawal fee of Cloudbet. But their current withdrawal fee is more than 30k satoshi, which is really high (you can't address it as a dynamic fee).
They are currently asking for over $11 worth of BTC for a withdrawal. At the same time, the mempool is showing less than 1.000 unconfirmed transactions waiting for confirmation. I won't change the info to dynamic but I will enter what I see on the page right now.
• I can assure you that the withdrawal fee is dynamic at Freebitco. Currently they are charging 132 satoshi for slow withdrawal and 564 satoshi for instant withdrawal.
I just checked the numbers and they are really low. Info changed to dynamic for Freebitco.
• You haven't added Duckdice in the table yet. Duckdice withdrawal fee is dynamic. Same goes for their sister site Tower.bet. The fees are set by the casino operator (software) there, but it is dynamic (fluctuate with network condition). Replace the withdrawal fee details of Tower.bet with "Dynamic withdrawal fees."
Tower.bet fees have been changed to dynamic. DuckDice will be added soon.
• Both Bustabit & Bustadice use dynamic withdrawal fee system.
This has been adjusted as well.
• The withdrawal fees for BC.Game & NanoGames aren't fixed. Both of them use higher dynamic fee for withdrawal. However, it can't be addressed as dynamic as the fee is quite high (like Cloudbet).
BC.Game's withdrawal fees are still 0.0002 BTC, same as the last time I updated the table info for them. NanoGames withdrawal fees are identical to those of BC.Game. The two sites look identical and seem to be using the same/similar type of software.
