I live in the USA and I have been fully verified with Coinbase. I am limited to $10,000 withdraw per day. I have withdraw small amounts to my bank before with no issues. But I am concern if my withdraw will get frozen if I withdraw $10,000 per day so that I can buy the house. I am not sure if withdrawing $10,000 per day will consider structuring since bitcoin is not cash but the bank will definitely file a SAR report since $10,000 keeps on appearing into my account everyday. This is my first year of trading and I do plan filing a tax form on my Forex earnings. I will definitely ask my bank and a tax accountant about it.
You made that much on forex or in crypto through investment? If you have bought that crypto in coinbase before than even though its big amount you will be fine if not or if you have deposited those crypto from other sources than they might ask your source of income.
Also check with your bank and make them aware of your incoming transfer and for the amount you have hire some lawyer for paperwork and tax implications.
