Coinbase has a $10k per day withdrawal limit. You have to contact them to get more. They don't specify how difficult or time consuming that process is.

It seriously isn't that difficult to get this limit increased.

Speaking as someone who watched a buddy go through this process it took him ~2 days to get his limit increased to the millions for a wire transfer.

In other words, it is not possible.
