How to legally sell crypto? amount +20mln rub.

Hello!

I wrote to Tink and this is what they replied:

At the moment, transactions with cryptocurrency are not prohibited, butare considered high-risk, including due toanonymous nature of the activity. Most transactions with cryptocurrencies are carried out outside the legal regulation of both the Russian Federation and most other states (the position of the Central Bank of the Russian Federation www.cbr.ru/press/pr/?file=04092017_183512if2017-09-04T18_31_05.htm), so we strongly do not recommend conducting them on bank accounts. We also inform you that according to the Letter of the Ministry of Finance of Russia dated May 17, 2018 N 03-04-07 / 33234, income received from the sale and purchase of cryptocurrency should be taxed.
Additionally, we recommend that you readmethodological recommendations of the Central Bank of the Russian Federation: www.cbr.ru/StaticHtml/File/117540/20210906_16-mr.pdf. We cannot say with certainty whether the bank will have questions if the client makes such transactions, since checks are carried out on an individual basis, based on many different factors. If the bank has any questions, it will most likely need to document the source of origin of the funds, as well as provide detailed information on transactions performed with cryptocurrency. This may include notarization of some documents. We strongly recommend that you follow the standards prescribed in the Central Bank's methodological recommendations No. 16 - MR in order to avoid checks by the bank. We also draw your attention to the fact that the bank has the right to set restrictions, for example, in accordance with clauses 4.5 and 7.3.9 of the UKBO.

I thought about different schemes, to sell for 500k, etc., but it’s not even an hour, I’m afraid that the money will be frozen anyway and which bank will give it back later ...
At least it will be done through Binance, as far as I understand, there is no difference?
Or are these troubles only through P2P and will not happen through the classic dispute exchange?
What are your opinions gentlemen?

Thank you.
