I don't expect to get a lot Rakeback.
I playing on Stake with more than 750K TRX Wagering and never know Stake have a Rakeback to the user. I only know the VIP Weekly Boost & Reload every weeks or end the month, the lucky things one of the support send me message for unclaimed Rakeback.
Got a nice Rakeback with more than 2500 TRX,
You have received nice rakeback amount. Your total wager amount is 750k TRX or it was in a single session? Cause normally I get 0.12% rakeback of my wager as a bronze VIP. Otherwise, maybe you are at higher VIP level and received much rakeback for your wager.
anyway see some post on Facebook about a stake how you choose some user who private promotion like deposit bonus and got reload maybe 5-10x times if I was not wrong.
These aren't official promotion of stake. Their marketing team give those bonuses randomly. Don't know how they select user for giving those deposit bonus and bigger reload. But when I was new to stake I have received a bonus mail, they offered me extra 5$ on my first deposit of 20$. And after that I have also received 10$ (2$ each day for 5 days) monthly reload without wagering significant amount.
Stake is generous to their user with various promotions and bonuses. I heard that many old and new user have received these kind of special bonuses from stake. It's their marketing strategy to attract and keep gamblers active at the site. Though I haven't played much there but I choose them as one of the best casino.
