Today I sent a small amount of USD from my Coinbase account, to my bank account. It says I will not receive those funds for 3 full days. Any other bank in the world would make that transaction almost immediately. Why does Coinbase take their sweet time? That is cruddy. Coinbase treats fiat like it is crypto. I am glad I do not have funds in Coinbase anymore, well, in a few days I won't.
It's their procedure. Like it or not, you have to accept it.
Anyway, I still wonder that Coinbase has customers even after they admitted that they sold their customer data. The crypto was meant to protect ones privacy.
