The mid stakes and high stakes games rake caps are 50% to 100% more than America's Cardroom. Although SWC's rake % is lower, the lower % is irrelevant at mid and high stakes games where the cap is reached the majority of the time.
The last rake adjustment by SWC was Nov. 18th when BTC was approximately $18,000. With BTC at almost $21,000 this is about a 15% increase in the BTC price. This results in a 15% increase in USD rake. However even on Nov. 18th, I believe the rake was too high heads up to promote game growth. Now it's just even worse.
I'm not sure why all your charts got deleted - The players lounge thread would be a good place to post them because that's useful information to all the players.
