The way to get around this, is to start an offshore company in whats referred to as an tax haven. Basically its a company that has an unknown owner normally some legal secretary or a lawyer firm stands as owner and somewhere there is a presigned agreement by them that transfers the ownership of the shares in the company to someone else that you can write in(TBD). So the company is basically in limbo between owners .
But yeah, that how you would do it, of course its a bit more, but that is the gist of it.Just make sure the legal company you hire or find on google isn't hacked, lol. Oh, and also, don't get a company card with this offshore company and use it to buy groceries, the tax people look out for that sort of thing :)
But you could likely defer taxes this way, by holding the bitcoin with the offshore company. You would then only pay taxes when you liquidated the bitcoin and paid yourself something.
Whereas if you held the bitcoin yourself, you would need to liquidate to pay taxes every year that it increases in value.
They don't know if you spent the rest of it immediately or kept it if you never put it into a domestic bank.
Because you can borrow against it instead of selling and without touching a financial institution, and this gives you liquidity without a tax event
Welcome to the 2020s
If your 'rainy day fund' is a stack of bills in a box, sure, but other than that there isn't much you can do with significant amounts of money that isn't going to involve some kind of transparency.
Literally trading those dollars for anything else involves gain/loss.
You're not going to be able to 'borrow against' anything under your mattress, it will have to be in some kind of regulated security, a bank account, or real estate - but it's moot - exchanging one asset for another is on the whole financial neutral.
More pragmatically, if you're 'borrowing against sums' you will be paying interest, there's almost a 100% chance you'll want to declare that against any other form of income for the tax shield.
Again, all of this 'hide your money' stuff is really the domain of tax evaders and likely the #1 flag for tax audits.
there is no obligation to report possible deductions.
you wouldn't here and you would remain compliant if you paid the interest with money you already paid taxes on.
the rest of your analogy just doesn't work.
But how do you repay the loan without liquidating the bitcoin?
... is probably illegal in almost every known reasonable country because it usually amounts to tax evasion.
So I'm not sure about this meme of "mega millionaires hiding their money is 'bad' if they identify as 'CEOs' but 'maybe good' if they identify as 'hackers'".
