I want to get a secure wallet for cryptocurrency. Many wallets make transactions anonymously, as a result, third parties can access them. I want to find a cryptocurrency wallet that will completely make my cryptocurrency transactions my property and will not allow access to this operation except for me.

I want to buy a nice Audi car. I've only ever had an Audi before and I love this car. But the last purchase was sad. I was deceived and had to overpay. It turns out the car was previously broken. Where can I see the Audi car catalog to immediately check its true VIN history?
