Fair point, that could be an option.

I’ve heard in the past that the off-ramp from crypto to fiat could be unreliable at exchanges but I don’t know personally whether that is true, either in general or for Canadian customers.

how do you cash out business amounts of money without a bank account though? if the bank doesn't want to work with him, it means he doesn't have anything to connect a Coinbase account to. Unless he wants to deal in large amounts of cash (which; cannabis clubs have to do, so it's not out of the question), he can't cash out.
