+# CoinJoinFees
+Comparing fees of different CoinJoin tools (Wasabi & Whirlpool for a range of pool sizes) by [@6102bitcoin](https://twitter.com/6102bitcoin).
+
+I have uploaded the full [python script](CoinJoinFees.py) used to generate these figures.
+
+To Do:
+1) Incorporate On-Chain Fees
+2) Incorporate actual Wasabi UTXO cascade splitting (0.7 -> 0.4, 0.2, 0.1)
