Optimizing Taxes Across HK, UK, and EU Without Moving

I need advice on structuring my finances to minimize taxes while handling crypto gains and international income.

I hold Belarus and EU passports, live in Spain with my partner and child, and have a mortgage. Before leaving Belarus had enough money to live for some time, this year sold another property and bought crypto via P2P (no money move between banks) without declaring the property sale in Spain. The crypto has gone up, and I want to use it for a business structure.

My plan is to open an HK company, loan the crypto to it, withdraw fiat (any business bank suggestion?), and then lend it to a UK company owned by the HK company. The UK company will operate, generate income pay Uk corp taxes, and pay dividends back to the HK company. I'd either pay myself (part just what i need to live) dividends from HK (and declare them in Spain) or avoid taxes altogether by fakely traveling between EU countries without establishing residency.

Is this structure viable? How could i go about my past non-declaration of property sales or crypto gains not cause problems in Spain? Is it realistic to avoid being a tax resident by kind of moving frequently?
