thank you

The problem is, either pay taxes but then they would look too deep in all earnings, or getting a solution that is secret.

https://localbitcoins.com/ i still need bank or paypal for that, but thank you, it is still good to know that site.

the best solution would be a debit card that is working with a bank (or other institution) that is NOT presenting the data to the tax departments.
Banks i guess, even if in a different country are forced to send data of all clients to the tax departments of the resident country of the account owner.

Thats why i asked for crypto.com or similar that may have a card that is connected to russia. Russia, as far as i know did not signed in to present the data to the resident country. Cards that are connected to russian banks must be the solution.
