I am sorry, but no cryptocurrency I know outside Nano confirms transactions this fast.
The only one I know has fast enough transactions apart from Nano is Monero, which takes 5 minutes at least, no matter the fee you pay, and it is a really decent tradeoff for privacy.
Yes, try it. There are big advantages to paying for services, over what I’ve said already.
As for payments, it’s usually: each year see email, copy the payment link into mycelium, click send, enter pin code.
Just try it. Pick one service (email is easy) and switch to a small privacy-focused company.

That’s okay, nobody starts off knowing everything.
Not only crypto but all payment systems take agrees to confirm - visa takes days - but as a customer you observe it happening instantly. Try it!
