Penso che non sia una gara a chi conferma per primo

If it's Synchronization with the Network then it may take very longtime if you have Bad internet (make sure to use the latest version of Bitcoin Core) because it's a downloading a 30GB File on your AppData .
If you have "Reindexing from disk" then It will take less time because it's just checking the files you downloaded before your the first step .
If you have the choice , I'd advice you to switch to Electrum to be honest , this is the decision I took lately because I saw that Bitcoin Core is screwing my shitty PC and always when I run it I found Corrupted database and have to sync again each tiime .

Maybe yes maybe not.

What pc are you using?

What size hdd or ssd do you have.

What is your internet connection?


If you have a killer pc with a killer cpu a big ssd lots of ram and a solid fast internet connection  it will be well under a day.
