Why people do always love to evade tax? Or do things which would able to minimize or cant able to pay up tax.
Even I, would just pay up and obeying governments laws rather than on minding on how not to pay or evade. Anytime soon you will really able to feel the metal barriers of jail.

I disagree with you.
Huge corporations try their best to avoid paying excessive taxes:

Borrowing cash against bitcoin, is a legal way to avoid taxes, as far as I see.
Make sure that you get the nitty-gritties right. The bitcoins should still be in your name (if at all there is an ownership trail). The loan should be at arm's length and should bear interest. There should be commercial substance behind the transaction you structure.
