What you are telling is correct but in credit card and debit card the transaction can be tracked but in bitcoin it can not be tracked

That's completely not true. Bitcoin transactions can be fairly easily tracked, especially if the robber is planning on spending the coins. There are companies that specialize in this sort of stuff. With all transactions being public, it is actually very easy to track Bitcoin transactions.

If we're talking robbery rather than carding, cards can be blocked. If people use them in physical stores then they're filmed. They also need physical access to them and you in the first place.

This whole thread is based on the premise that they have physical access to you and can physically rob you. If a card is stolen, as soon as the money is spent and the robber has the goods that they want, blocking the card is just as good as letting them steal the amount of money from you as they spent on the card. Furthermore, they don't need to use the card in a physical store, they can go online and buy things with the card online. And with debit cards, they just need to go to an ATM and withdraw as much money as possible.

With crypto none of that is necessary. It does make nefarious and anonymous demands much easier.

You can be tootling along in your self driving car and then suddenly receive an email threatening to chuck you off the next bridge unless you cough up.

And if you don't cough up, you can die. And if you do, you will probably also die. But if you are dead, no one will be able to touch your money with crypto. With fiat the attacker can go over to your dead body and retrieve your credit and debit cards from your wallet.

Dont you think mobile banking and wallets are already in use by major population. That already makes us vulnerable to such threats.

That's a good point. If you physically rob someone and can get the password to their phone, you probably do have access to their bank accounts as many people access their bank accounts from their phones too.
