The highest i can get from freebet was USD 2,300. Got a freebet at USD 10, rolled it like crazy lol.
Usually in Asian website they are quite royal about freebet. Im not really sure about crypto casino.
That is a lot of money to get without a deposit, I mean in my country that would be enough for one person to live for 3 to 4 months with a surplus if they are frugal in spending. Those kinds of gambling sites are a really good site because they are confident that their client base is going to go back for more because they are free to do so.
