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 big and I am glad they allow such amounts because most of the bonuses have restrictions like you cannot cashout more than $50 or something like that.
As I remember correctly, I ever withdrawing about $20 from vipgames.io without deposit anything, I get the bonus register promotion from a manager, I am not sure exactly how much I get, maybe about $1-$2 then make it x10 by playing it on crash games. That promotes makes me addicting to playing more.
You get addicted and their goal of giving free coins is complete haha because all they want is players to get to know the site with the bonus and later deposit their own money.
My best bonus without a deposit has been like $100 in the past when directbet.io used to exist and they have me a free bet worth $50 and I placed that with 2.00 odds and won.
