I think this post has actually explained everything about the burn steem initiative in a very simple way to users who are new to the world of crypto currency.

A simple scenario for user who think this initiative wont help steem is to have a look at the binance coin( popularly known as the BNB ) . Binance themselves make sure to buy back bnb at the end of a period and then burn them, now this initiative has caused the bnb token to have a very strong presence in the market as we can see that when most coins are falling the bnb token always stands strong.

This same thing can be replicated for the steem ecosystem.

The more we power up and burn steem the scarcity of the number of tokens in circulation will reduce causing the price to rise and at the end we will benefit from it.
