Same in the United States. The Big Four banks are not happy seeing large ACH withdrawls to Coinbase.
· JPMorgan Chase
· Bank of America
· Citigroup
· Wells Fargo
It is not so much that they don't want to see large withdrawals to coinbase it is that they do not like to see a lot of withdrawals to coinbase and then a large deposit from coinbase. This makes it look like you are conducting business out of your personal account (which you are) and it looks like you are potentially check kiting via ACH transfers.
This is probably right. Having a lot of money move in and out of your bank account will look very suspicious to a compliance officer regardless why you are doing it.
