To cash out crypto without paying taxes..Simple.Set up offshore Charitable Purpose Foundations!
Choose mission like "strengthen the capacity of people throughout the world to meet the challenges of global interdependence” (that is Clinton foundation) avoid too specific Mission like “raising money for children battling life-threatening diseases” (that's Trump - you might end up struggling to proof that)
Once you transfer your bitcoins to your foundation - travel the world first class, stay in most expensive hotels or do anything that you enjoy with a message that you do it to “raise awareness”.
Obviously even the elite have ways preventing them paying full tax. It's a flawed system
