The deposit made in BK8 will be credited 100% in special bonus with a requirement of 6x? I understand that a minimum wagering requirement is the deposit +100% and this is x6, isn't it?
Yes, if you join this bonus program, you must be able to make at least 6x the value of the deposit you made. Let's say your deposit is 180K IDR and following this 100% bonus, then you must place a bet with a minimum value of 180,000*6. If at the time you experience a big win in several spins, then you must meet the TO first before you can withdraw all your winnings.
Regarding BTC it is very encouraging that they do not have any withdrawal fee, this means that in case I want to make a deposit without wanting to take the bonus and if I win 50USD in Bitcoin, I have the right to withdraw the total money without any rate? BK8 is raising a lot of level, there are many looking to play here, if they put as their main slogan that their bitcoin withdrawals are free, this will call many people to play.
If you make a deposit without a bonus, then you will be charged 1x TO, so you have to play the same value as your deposit value 1x. The BTC withdrawal rate will be set automatically, so there is no need to do anything. this rate will be locked in a few minutes. So, it would be safe if there was a flash dump. For example, you withdraw BTC and are locked at a price of 20,000, when BTC price after your withdrawal drops to 18,000, you still earn at rate of 20,000 and there is nothing change. this is the advantage of BK8 in terms of withdrawal. both fiat and crypto impose zero fees for withdrawals.
), the complete absence of commissions is a strong argument to attract new players who own bitcoins. And those people who do not really want to bother with the use of altcoins.
