He can try to wager at least $3k per week. He can claim more than $1 since there are promotions posted on a different platform that is claimable if they wagered at least $3k regardless of the account status. Stake streamers also give claimable bonuses on a first come first serve basis.
Wagering weekly 3 thousand dollars, for a dollar return doesn't sound like someone would do just for that, if they wager 3k anyway then they should maybe remember it, but even in that case if you forget then you should be fine because anyone who wagers 3k per week would be able to afford so much and not care about the dollar they would get, that’s just too little.
But let’s remember, this is something stake doesn't have to do, they do it for promotion reasons but the only thing they are responsible for is offering you games, and keeping the house edge provably fair, that’s it, anything extra we get is a blessing and also a marketing done by them.
