Hello
I did a bit of googling and found a few things....

But how much income tax will Mr. Zuckerberg pay on the rest of his stock that he won’t immediately sell? He need not pay any. Instead, he can simply use his stock as collateral to borrow against his tremendous wealth and avoid all tax. That’s what Lawrence J. Ellison, the chief executive of Oracle, did. He reportedly borrowed more than a billion dollars against his Oracle shares and bought one of the most expensive yachts in the world.

If Mr. Zuckerberg hands Kanye West $1 billion as a loan, is it taxable income?
Nope, loan proceeds aren't income, provided that it’s a real loan. That’s a key distinction that lands many taxpayers in trouble with the IRS. The $1 billion in loan proceeds would not be income to Kanye, and he should be able to deduct the interest payments. Mr. Zuckerberg just would report the interest as income.
Ok, thank you, very interesting;it has the advantage of transparence.
however there you deposit the cryptos outside in a private firm, with its own risks ?
also there is a cost (16 %), and back payments, maybe not the principal argument.
