Yet another bitcoin to bank question

Is there anyway to bank profits (if and when i decide to convert them) - with a bank that will accept my money from an exchange? lets say.. Kraken or anything in that area.
the amounts ill be planning on are between 200k-300k euro

I would take any ideas or plans of work - I have no experience in business, I've been 9-5ing since i've known myself.
but im reaching a point where i could cash out some money and still own some bitcoin, while PREHAPS even moving to 1-5. :)

Really don't know where to start. felling kinda lost.
(been using emi's so far, but that's really small change.)

Thanks everyone,

Use OTC desks

As an OTC desk owner, we perform an off-exchange transaction, so you receive your money in your bank account from the bank account that is not linked to a crypto exchange. Therefore, your bank is less likely to ask questions about the transaction when it does not come from a crypto exchange.

Thanks, that actually sounds "less risky" than receiving a bank transfer from a crypto exchange.
Can I have some details on your OTC like escrow, fees, etc?

Also another important question is - what do I tell the bank when they see a large transfer? or would the smarter idea would be to do it in batches?
still - questions might arise?
