The result of burning coins is that they will reduce the amount of coins from the supply. As a result, the supply of that coin will decrease and the price of the coin will increase.
If a coin is having a real world application then there will be no need of going for burning it. In my opinion burning is a process that it is being conducted to create artificial demand. This is definitely a kind of manipulation but unfortunately no one is ready to realize the fact but falling into such a trap.
We all know that 50% of the bnb coins were burned. And as a result, the price of bnb coins is much higher now.
BNB must be an exceptional case. It is having a real world application like you can get up to 50% discount if you pay in BNB in binance trading. Still, not sure why binance is planning for scheduled burning time to time.
