I would say that bitcoin exist digitally since it is stored digitally and it can also stored in physical devices which contains the private key.
Hello there
Sorry to disturb you, can you recommend a wallet?
Electrum[1] for desktop, and BlueWallet[2] for mobile.
I'm sure you're probably excited to buy some bitcoin, but please educate yourself first before actually buying. The last thing you'd want is to lose your hard earned money because of carelessness.
