how to cash out properly and pay my taxes.

Hi everyone,

I recently made a life changing ammount of money following a tweet of a guy on Arxiv and i consider myself very lucky to be in this position, specially that life hasn't been easy.

Now, my question is in regards to how to actually sell everything into bank acc. I have both binance and coinbase but considering that I am going to want to deposit over lets say 150.000 should I use both.

Any other tips in regards to banks that would have this go smoothly?

Banks in EU.

I would just hate for the transaction to be blocked or worse and i wanna take some steps to make sure.

Thanks for any tips
