As there is now way that you can withdraw that amount of money without raising red flags regardless of the country in which you are living, also it does not make too much sense to sell all of those coins and then think about what to do with that money when it is already invested in bitcoin, so at most I would try to withdraw 10% of that amount with the precautions I mention above in a process that most likely will take months, as going from earning a small amount of money to a fortune will without a doubt bring a lot of attention to yourself, and you will have to be ready to explain the source of those funds over and over again.
The only reason I would cash out that amount of Bitcoin would be to 'rebalance' my investment portfolio and mitigate risk, even though this would cause a taxable event, and would be a high price to pay.
