No, you wont get a knock (knock, knock) on the door. If you are employed, the chances are the only credits to your account is your salary, yes? So your bank knows where your funds come from. If they are happy it isn’t layering on the way in, then its unlikely (but possible) to be layering on the way out. Why you do it is no-ones business but yours, its not illegal to change monies to crypto – yet, but @footflaps is correct, it may well be seen as a red flag – drugs, terrorism, people trafficking, etc, why do you need to do it? that’s not me asking by the way, that’s what your bank will be thinking…
the main reason banks and govt’s dont like crypto, is because they cant tax it or profit from it, end of.
