Is that means, that from Platinium IV level we get permanent daily bonus from the Dedicated VIP Host?
The dedicated VIP host will renew your reload in each week. You will have the option to choose daily, hourly or 10 minute reload from your VIP host for a 7 day period. Your reload will expire after one week. You have to renew your reload each week by contacting with your VIP host on the telegram. You may have the VIP host permanently, but the reload amount isn't fixed. The reload amount depends on your last 7 days gameplay (profit/loss) activity.
Another benefit is Bonus from VIP host in currency of your choice - is that only one time bonus, or Dedicated VIP Host often gave us a bonuses?
You will get a dedicated VIP host after reaching platinum IV rank. The host will give you a rank up bonus for reaching platinum IV. And you will receive only one bonus for each rank up. It means, the host will give you a rank up bonus again when you will reach platinum V, platinum VI and Diamond VIP level. However, the VIP host occasionally (once in a month) gives an additional bonus to it's user, they post the bonus link on their telegram channel (each VIP host has their own telegram channel).
