Booking Etsy, Fiverr, Upwork and other platforms

Dear Sir/Madam, I searched the forum but couldn’t find the answer. I work with various freelance and pod platforms. They charge fees for payments from “customers” as well as for transactions, plus VAT on top of that. How should I book these?

Do I only enter my net deposits as income? Or do I enter the full amount, with the paid vAT and any fees as costs?

And additionally: what do I do with income from crypto mining? Do I enter it entirely as net income, or is it better to include it under other income in my personal income tax return?
