"N26 has had a full European banking licence since 2016 – and any funds you have with it are covered by the German Bank guarantee (up to €100,000)." [1]
If you need these, you know it. For example, if you keep balances in multiple currencies or want to transfer money between EU and US banks or have a low-fee multi-currency debit card. Paypal doesn't allow any of that.
Not sure you can use paypal to put money in an account and then use a card to withdraw it at cash points and pay for coffee etc. Also I once sent a US friend $500 with paypal and got charged $25. Transferwise would be way cheaper.
I recommend Transferwise because they support ACH transfers and US$ balances.
