The last update seems to be not fully updated, I have 133x multiplier but it is not on the list.
Before the update, I'm sure the 50x is mine (which is now in the 4th place), I have no idea why my 133 is not there after today's update.
Below is the proof that I hit 133x (on 23rd), I saw the one with the 150x because I was there as well when he/cashed out at 150x:
I guess it depends on the currency you use, I see there are some players playing with bet worth less then $0.2 but his currency is INR (Indian Rupee), his bet was 10INR which worth $0.12 at the current rate.
