There is some scientific backing to this. Basically by isolating ourselves in these little bubbles of death, we stop seeing the other people as people and this removes any moral/societal blockers to descending into a pit of rage and calling for the termination of their bloodline, death by inept firing squad, etc.

Yep, I was going to say the same thing. Wise (formerly TransferWise) is a pretty big player in this space.

You get a bank account in each currency you want, and you can do transfers between currencies all within their service.

I use them to move money between USD and EUR for bills, and the service fees are reasonable.
