Oh yeah and to explain why I'm alarming:

I invested on the Bankroll a bit earlier but wasn't monitoring anything. Then I started monitoring and didn't see any weird behavior (except exceptional returns) until 22th of March, while the jackpot was getting around 2.5BTC. Did they change internal bankroller's rules realizing something ??.

Look at some of my snapshots:

On 2/16/2020, the site's bankroll was 55.55343753 and the Investing site's profit was 37.03121129. My ROI at this time was -0.19%.
On 2/24/2020, the site's bankroll was 58.02477003 and the Investing site's profit was 42.25053009. My ROI at this time was +4.52%.
On 3/2/2020, the site's bankroll was 67.7317264 and the Investing site's profit was 52.80680479. My ROI at this time was +13.17%.
On 3/9/2020, the site's bankroll was 14.99122993 and the Investing site's profit was 47.72030075. My ROI at this time was +9.69%.
On 3/17/2020, the site's bankroll was 22.4784 and the Investing site's profit was 58.6876. My ROI at this time was +34.58%.
On 3/21/2020, the site's bankroll was 33.1453 and the Investing site's profit was 62.3768. My ROI at this time was +42.58%

Then things start shifting:

On 3/23/2020, the site's bankroll was 33.6784 and the Investing site's profit was 62.9199. My ROI at this time was +36.29% --> WTF loosing 6% while the investing keep growing !!!.
On 4/2/2020, the site's bankroll was 32.7101 and the Investing site's profit was 63.5334. My ROI at this time was +30.19%.
On 4/12/2020, the site's bankroll was 27.39536447 and the Investing site's profit was 63.58591385. My ROI at this time was +21.33%.

As you can see the site's benefit keep growing and we, as investors, keep loosing.

We need explanation.
