Those wallets have a public key and a private key Public key or address can be shared with anyone to receive coins whereas the private key is used to transfer tokens to someone else and therefore it has to be confidential.

I love your explanation on this, when other normal crypto wallets have public and private keys, the null or dead address used for burning only have public address and no private key which means no one can access whatever assets that enters the wallet and that makes them forever destroyed.

The total supply of BNB is 200 billion and Binance proposed to burn 100 billion coins. Binance is known to burn more than 250 BNB coins every day.

The aim of BNB is to burn half of the total supply and this is when the auto-burn would stop. The daily auto-burn of BNB is from the portions of the gas fees for block validations on the BNB Smart Chain, something known as BEP-95 burn.

Undoubtly it will reduce the supply of Steem but we know that the total supply of Steem is not limited.

Truly, the unlimited supply of Steem should be something one should worry about because more of them are generated every day but in medium term, I still believe it will help to maintain the price till the inflation rate decreases to 0.95% and Steem creation per block would be reduced then.

It's always good to read your post. I wish you all the best.
