It looks like it as everytime Bitsler reach a billionth bet they try to create a promotion from it. It is one of the best way in celebrating a milestone and that is being able to give back to Bitsler's community. By that time happens chances are Bitsler will have multiple promotions as the World Cup is still far from over.
If Bitsler will go with another Billionth Bet promotion, it's not surprising anymore. Bitsler is good with giving back to the gambling community. Bitsler may have been the target of DDOS attacks recently but it didn't stop the players to wait till the site is up and running again. Just look at how many bets Bitsler handled so far? It's just 170 Million bets shy to reach 27 Billions bets.
Sometimes its not even DDOS but its basically tons of people flooding the autobot to get the winning roll.
I have pretty much given up trying and winning a milestone number because its impossible to time it properly.
Even if you calculate that there are 100 bets/second and when it gets near the milestone number, in that minute it will go up to like 500 or 1000 bets/second which are all mostly bits competing to get the winning number.
What needs to be done is limit the bets to like 1 bet/second during that hour that the milestone numbers will appear. It will give everyone a more equal and fair chance.
I think it's not tbat hard to determine where it's ddos attack or massive traffic amd active gambling on website. Also limiting isn't a good idea to my mind. What about to upgrade current servers and add some new ones? There is no doubt it will solve if the problem you mention exists, as far as I know it works against DDOS too (not a technical guy).
Nobody upgrades their servers due to a DDOS attack. What they do instead is simply use something like Cloudflare. Its that annoying message that makes you wait 5 seconds before forwarding you to the website.
Its almost impossible to upgrade your server to the point where they can withstand a DDOS attack; unless they are Apple, Google, or Microsoft.
The problem with the milestones is that many people use multiple accounts and use VPNs and have like probably 50-100 different alts, and right before the winning number they basically bet like crazy trying to strike the winning number. Then they just disappear and won't gamble again. While the honest gamblers don't reap the rewards they deserve.
Hence this is the reason why you need to set a really high bet base limit or just limit the amount of bets per second during that period where the milestone will be hit.
Most likely it won't get done because its way too much programming work for such a simple milestone contest, hence they just leave it as is.
