I used mobile wallets. And I dont agree with you. I think Its more dangerous on pc compared to phone. Since pc are most prone to viruses compared to phones. And theres this 2fa verication already by google on your phone which is so hard to hacked by hackers so better activate it.
i think PC wallet and mobile wallet is same my friend, especially for a people with a lot of online activity in their PC or mobile
a virus or phissing link will always lurking us my friend
and because of that maybe the most safest wallet for cryptocurrency is paper wallet and hardware wallet
