Keep in mind that openly sharing your knowledge regarding these matters can render it useless if too many people start using it (especially if you decide to be very specific).
I would prefer strategies that will work independently, well enough to make it impossible for government to find out and stop. Not strategies like "keep your money in this persons bank, because we can trust him no to report," after which the person is found out and arrested. For example, how to buy through exchange without being noticed, how to buy food and sleeping place without converting bitcoin into bank money, how to trade without trade being noticed and needed to be reported by business. We have many libertarians and anarchists on this board. I am sure they have many strategies for how to evade taxes without being caught.
Later on, maybe such strategies will help with project I am working on.
