Talking about whales, I do not think whales can be on the top list of the most profit player by betting ton of money and win it (without jackpot) in single bet because the max allowed profit in one bet is limited to 242mBTC at the time I write this post. So it impossible for whales to be on the top list by single bet because the current top position has more than 2.9BTC profit
It is a fact on this site that most players are playing here for the jackpot only, I have not seen any players who play like normal gamblers who love to play crash game without jackpot.
Even if they can't win all by one bet, they can definitely reach there with enough betting. These guys don't care about how much they win or lose at these levels, we are talking about whales and those guys can wager for 5+ btc all together with a series of betting, they may end up losing money as well but I feel like if they have enough money they can risk a lot more and reach those levels.
Sure, some whales will not be there because they will have bad luck but we are talking about whales not a whale, so eventually one would wager enough to get back what he lost and be in profit. Hall of fame also shows that habit for example won 2900 mbtc from the jackpot but his profits are lower, which means dude lost money as well, but he still won. A whale could get the jackpot by playing all the time with high amount and have a high chance as well.
Just checked "Hall of fame"
Seventeen out of the top 20 high-profited users have won at least one of 50 biggest jackpots ever won. The biggest cashout is smaller than all first 21 jackpots won.
In my opinion, the jackpot has made the game really exciting.
In other crash games in other sites, if you play for a long time, you will likely lose 1%(The house is usually 1%). But in Rocketpot you have the chance to hit a jackpot and make a big profit, however if you are not lucky you will likely lose more than 1%. Because for paying the jackpots, they have to have a bigger house edge than other sites.
