SEPA is far superior to what is being used in the US and much better regulated.
1. There are no intermediary banks
2. Each bank has 24h(weekends excluded ofc) to process your transfer, so you have your cash in 48h max(i had transfers that took 1-2h)
3. SEPA transfers cant cost more than domestic transfers, which is usually 0 fees
etc.
So far no real difference, except maybe the "much better regulation" so is there anything specific on why you consider that as better?
There are exceptions for DDA accounts with bad credit where they bank asks for ACH delay to be agreed, if you have such a DDA account, usually delay agreement can be dropped within months to a year depending on creditworthiness. 1-2 hours is not so uncommon with ACH either, depends on the bank and the relationship.
I like that you have pride in SEPA, but would like to learn more about why.
The bitcoin-broker service is pretty great, and I am contemplating opening up some of my EU accounts to it, but I don't think SEPA gives any specific advantage to that.
