Bank transfer is different to cash deposit either way it will raise eyebrows especially in a single transaction.
I've heard banks have deposit or transfer triggers for certain amounts for investigation, this can be personal or business accounts.
They're shit hot on this in the UK now, not sure about other countries.
EDIT: You need to have a cast iron excuse where the moneys come from and for what.
Based on my experience with banking in Canada, whenever a transaction larger than $8k appears they usually place a "hold" on it and call me asking me where it's coming from, bitcoin related or not.
Yes I agree, I've had calls from my bank for £2k+ ($3100) transfers asking what its for on both personal and business accounts with different banks. This has been the same here for a few years.
They are obliged by law to look into it, I'm not sure what the exact trigger figure is.
