IPhone 17 is around $1700 to one device, those that mean I can keep $1600 on my iPhone and feel safe? This analogy doesn't make too much sense. I think if we are having funds that we are not going to move from one wallet to another often like deposit to exchange and withdraw, it's better the money remain idle on offline wallet until the coin is ready to be spent.
Honestly, I am an iPhone fan, but I feel its price is extremely exaggerated. There are other phones brands that offer more efficiency at a lower cost. It is nice to find the MIE feature in the iPhone 17, but for those who want to buy this phone at this price, why not buy a hardware wallet for less than $100 that can actually keep your funds safe? You don’t need to spend $1,700 on an iPhone.
Although Apple provides a more secure environment than Android, this does not prevent the existence of vulnerabilities, as OP mentioned, that scammers , scammers can still exploit them. There are no system is ever 100% secure. Attackers always find a way to hack these systems, so I agree that offline storage (cold storage) is the best option, and it doesn’t cost much at all.
