Sounds great! BB Americas has something similar for Brazilians wanting a US bank account, but other Latin American countries don't have services like Aeldra or BB available yet.
I don't think that is winding down but more of a compliance with their partner bank account. As long as you have transaction done by regularly you don't need to worry I think.
Aeldra is winding down its operations due to a decision driven by external factors. This action is not specific to your account and applies to all Aeldra accounts.
