A regular bank transfer? I know the US doesn't really do that kind of thing, but here in Europe I can send money to another bank account within 10 seconds.[1] And it doesn't even cost me or you anything and all I need is your IBAN.
Here is a Monero address. Things sent there ends up with me. I advise against sending anything to it. Are you going to post your IBAN and account details?
I don't actually know what my IBAN is, but assuming it is my account number I'm not comfortable posting it here like I just did for a crypto address. This technology is something other than what I've had access to before.
Have you tried sending money across the world in 10 seconds, to somebody outside of the EU? Most answers to this are PayPal, Wise, or another multibillion dollar private enterprise.
At least I know that those 5€ only change on a term of months, or with inflation.
Last time I looked at ETH and BTC I spent a good 30mins trying to figure out how much the transaction would actually cost me and if it depended if I clicked GO at an opportune moment. And yes, I admit that this might have only been a difference of cents, but I wouldn't know that beforehand.
