I don't think that's going to do much good. For the wealth tax for instance they can go back 5 years, and if funds are abroad they'll go back 12 years.
And they'll tax you on funds you don't longer own, such as bitcoin held by lost wallets or lost private keys? That seems ridiculous.
It would be ridiculous how can they require INCOME tax or CAPITAL GAIN tax on something that you have not earned? It would be theft and not tax. For what reason are hardware wallets which are suppose to the best interest for peoples security allowing this to happen without any resistance? If they are suppose to be the most secure then privacy is part of security.
