I had to do it: I could not leave the bankroll challenge unfinished, especially when I was so close to make it. So I went for SvenBe solution and completed the BRC:
Week 22
Hands since start: 38,769 + unknown volume
Profit since start: +$461.41
Profit since last report: +$99.40
Start BR: $50
Total BR: $511.41
Since there is no tracking possible on chico network, or lets say I dont want to pay for a yearly license hand tracker/converter, I proof my claim with screenshots from cashier. The Deposit:
followed by current cashier: 
Now that Im eligible for the $50 TAF bonus from this promotion: https://forums.pokerstrategy.com/de/forum/thread.php?threadid=1828206&goto=firstnew
I consider my challenge as completed and can now sleep peacefully ![]()
I still would like to grind but I dont think I will continue on sportsbetting after the promo/bonus since rake is pretty high, the challenges/missions are not doable with such little PLO traffic. With german restrictions, me being somewhat sceptic when it comes to clubs/apps the best option would still be stars but I really dont want to support the regulation BS by just continue playing.
(german) Poker players got rect every year for the last 10 years and continue playing on a regulated site under these conditions would be me sending the wrong message. If stars decides to cut the bonuses for german players completely just because they have to according to gov it would be fair to adjust rake for german players but it wont happen so I wont come back to the regulated online tables.
