This is of course entirely possible. But I can't imagine what they would find since he has the full balance as available for withdraw, no bonuses were used or are active, it wasn't a promotion, and crypto was used on a probably fair casino that's been around since 2014.
And yes I expect them to request a testimonial etc.
It does not matter how "legit" his win is, they will find a way to get out of it. I know several instances where these "smaller"
casinos had "Jackpot" winners that got screwed out of their winnings. They will find some technical thing in their ToS to have
a legitimate reason not to honour the pay out. Please come back to me and prove me wrong... ...You are not the first
person to come to this forum with announcements that you or someone else won some "Jackpot" and in the end, these
casinos find reasons not to pay. They are not even interested in settling for a lower amount, because they do not want to
pay anything.
that he was eligible to claim the full amount.>
