i never earned these much money but i want to know how to manage and what is the process of giving income tax and crypto tax.
Most of these people have a dedicated CA who works for them and manages their taxes. Going by the calculation system for such an income the New regimen would be better suited to tax, but this also depends on how much they want to show as income.
Crypto tax comes in when you show the capital gains. Unless you are selling any you would not be getting into any taxation.
