Point is I am planning to Buy a Ledger Nano S instead of the X as what someone Posted in a thread somewhere it's just "storage capacity is bigger for the Ledger Nano X".

Not only does it have more storage capacity but also allows user to connect with another device using Bluetooth. For some people, it is a clear security hole.

Well.. security hole is a bit exaggerated.
The interface itself is not a vulnerability. But it poses as an additional attack surface.

I mean.. if there would be a vulnerability in the firmware which allows me to trigger a transaction without confirming the button, one might be able to abuse it by standing near the device, while a direct USB connection would be required without bluetooth available.

In both cases the vulnerability would be extremely dangerous. But bluetooth would make it even more serious because it could be exploited without even touching the device / a computer.

This is just a theoretical case on why bluetooth might be more dangerous in some circumstances given that a vulnerability exists. This doesn't mean that bluetooth itself is bad / vulnerable / etc.

However, i personally prefer a hardware wallet without an interface besides USB. More security doesn't hurt IMO.
