Process of reporting passive income from crypto in Finland?

I’ll put these in a form of questions:

Would it be a problem to send an amount of money from Coinmotion to OP bank account?
Do I have to inform the bank that I am sending money to my account on a regular basis? Or what amount of money I’m sending requires informing beforehand (over 10k eur for example.)

When do I have to report that income to Vero?
Would they require me to provide them the source of all my past Txs related to the generation of that income?
How can I know how much tax I have to pay to Vero? (I would like to pay it immediately)
