Is Satoshi Dice Still Fair?

On 20th July, Satoshidice made a big change on their website by decreasing the winning number drastically.

Following are the changes:

As a daily player, I notice that one of the player was winning almost 50+ BCH per day from betting on x25, x3 and 1.5.

During the time Satoshi Dice had around 450 BCH in their wallet, and as the player was aiming for max win return (10 BCH). Therefore, in 4-to-5-day course the player cleared out the Satoshi Dice wallet to around 5 BCH and transferred to his address.

NOTE: This is the player address: “qz37fjswavhu2q88eu5y378kfnl752xul5vf23wnua”

I do play and observe the site on daily basis and notice a significant change on site as none of the players seems to get back their own initials on their bets. – See attached image (captured on: 12/08/2021)

The reason my claim for this is because after the changes in the site, the same player lost around 80% of their winning in just few days which helped Satoshi dice recovered more than the amount they lost in less than a week. Currently they have 520+ BCH in their main wallet.

Since the changes has been made, it seems like the dice is no longer fair.

To support my claim on this, I tried to dig deeper and captured my own live bets on which I found the number has been decreased also, does not match the percent shown on the website.

The followings are the win rates before and after the changes made on site:

% Shown in site for x1000= 0.10%

% Captured on live bet for x1000 = % Before changes = 0.000991

% Captured on live bet for x1000 = % After changes = 0.000976

As seen above, the site shows 0.10% winning change in x1000, however my research on it shows the winning percent was only “0.000991” before the changes were made but, after the changes even though the number did not change a lot “0.000976” it is not fair to provide false information to players as it is no where near 0.10%.
