I assume you also have a shady SOF and you're starting from zero. If you show your crypto to banks/notaries etc. they want the documents that justify how you purchased your crypto in the first place.
The options are:
1) with shady SOF or with no SOF -> Move to a country where you can get the residence (with LV passport I assume it's not going to be a problem) and which has low corp tax and 0 dividends tax. Create a company and a fake business (IT, marketing and/or anything digital without any relations to crypto, with proper agreements etc. - be creative) to cashout your USDT. Find someone who you can invoice and who can offer a reasonable fee. Sometimes you can do USDT->corp. EUR at 0% or people even pay you 2-3% for your USDT. Then pay the small corp tax + don't be a scrudge and pay yourself a salary as well. During the year you can slowly cashout your 900k eur let's say at 10% and you'll have clean funds in your new bank account from your dividends payments to yourself.
2) with bulletproof SOF (proof of transfers of your EUR/USD to crypto exchanges, from your declared income btw, all your trade history and wallets) -> Find a low personal income tax country where you can get residence with crypto-friendly banks and cashout directly. This is the easiest option and then there won't be any problems with AML/KYC for your land/real estate purchases.
