He should have the money. I tried to create one but received "insufficient balance" notification.

As predicted, people start to use it to promote referral code
Well, if lots of people use your code, you might get profit in the long run assumed they will still use your code, and not enroll with alts only for joining the contests.

You are right, in addition to this Ripple despite its problems with the SEC the price or its movements at the level of market speculation are not affected, that is, Ripple investors as well as traders only care about the currency for their utility, I have been seeing a lot of XRP analysis and eventually the price is only affected by the movements of BTC, it is something normal, in this case Rollbit decides to adopt XRP for that same reason, in addition to which you indicate that its fees are relatively very low, and in a casino this is paradise. I applaud this performance by part of Rollbit.

I created one challenge for testing purpose few days back but it seems that no one is interested, perhaps because the prize is not attractive as it was few bucks only and with a 1000x multiplier to hunt. I asked support about a way to delete or edit it but it seems there is no features to do it and they deleted it for me eventually. Support said that there should be a button to delete it but I could not find it anywhere.

So anybody looking at the leaderboard on Rollbit? The so called Rollbit Boss the big whale has already crossed $140 million wagered and claimed extra bonus of $110k till the time and only two are into $100 million wagered club.At 3rd spot is @Ayezee with $64 million and still far behind them even after one of the big ones few days back.He has also created 1-2 challenges to participate in that also.Will the Rollbit Boss title claimed by some other big player?

@Johnyz you’re absolutely correct and this is something I realised that these guys don’t bother for the title anymore, for them it’s just a pass time and another way to flex their wealth. Furthermore whenever you see whales participate it’s best to avoid going war with them, because sooner or later they’ll pump in their massive funds and leave you in the dust.

It's a really "big worthy bonus". Even though they wagered a lot of money already, it doesn't necessarily mean that they own that amount of money. Betting is winning and lossing, most of the time  you'll only got your capital + some or big wins. What I wanna say is that that $110k bonus can be wagered to a million $$ or more.

Are you sure there is someone who has reached 1billion wagered while the top leaderboard has wagered $140+ M only?
No one has wagered that much (based on the leaderboard), if there is someone has wagered that much then he/she will be on top of the leaderboard.
It seems that there was something wrong with your eyes when you look at those mentioned players.

Yeah, wagering 1 billion dollar is quite a long run to go. It can't be easily achieved by anyone. In fact, just to make as example, a casino recently just achieved 1 billion wagers for their site, that numbers are the total wagered USD of all of their players. Imagine comparing it to total wager of single user.
