proper asset protection strategies that rely on more than perjuring yourself and violating court orders can apply to other assets than cryptocurrency when it comes to protection from creditors, ex spouses, and potential lawsuits. This after all is a forum about the offshore world I would imagine you can find some more about things like Foundations and Trusts on here.
Your entire view on cryptocurrency revolves around a paranoid delusion︀ that 1. you can take on the full might of the state 2. the state︁ even cares about your existence. Interestingly enough there are instances of US persons with judgements︂ against them who have stuffed their assets into Cook Islands asset protection trusts properly and︃ have managed to pay out $0 of those judgements.
Sticking ones $10M in BTC and︄ lying under oath about its existence, amount, or your ownership of it is not an︅ asset protection strategy it's just a crime. It will not protect you from the prison︆ sentence when it's uncovered you did this. In reality though this day for 99% of︇ BTC hodlers will never come because they are irrelevant to the government and are small︈ fish who if the government wants their money and cant get at it instantly no︉ issue they will hit you with a tax lien and garnishments. They wont even waste︊ the time looking for your $30K of peanut money in internet coins... they will wait︋ until you cash it out to your bank to buy food with fiat and will︌ swipe that.
Asset protection for all types of asset classes exist and most UHNWI use︍ them they arent all in BTC. UHNWI are some of the most paranoid people too︎ and for good reason. Yet for some reason BTC isn't even bigger than golds market️ cap so clearly they arent buying in mass.
