Bitcoin is omnipresent and therefore maybe not real and therefore you can say you do not have any because you cannot have something that is everywhere

I upvoted your message ... I believe you are right. You only claim what you are bringing with you. It my friend is not with you. Do the rich claim their bank accounts that the US has no jurisdiction over. The bankers do NOT regulate bit coin. Do you concur @kingscrown?

Makes sense.

You are right , its basically like forcing you to declare your bank account balance.

I agree with you too, but that argument wouldn't hold up in court if you somehow did get caught holding BTC.

Isn't it by fact money that you don't really own? It's virtual. At the time you have these numbers "related" (and nothing more) to your "account" there is no real, existing value in your possession. You only REALLY have any capital, if your transact into mainstream currency.

It's like charging you at the air port for holding microsoft stocks.
Or am I missing something? I don't think it suceeds.

Crypto is definitely an asset that you own and is regulated either as a commodity or as a currency depending on where you live. But you are correct that it is ridiculous and similar to asking you your bank account balance.
