Burning of coins is a good strategy to reduce coin supply and there by create more scarcity for the coin, and this in turn makes the coin more valuable in the market, but sometimes, burning of coins don't always affect price in a positive way that much, like the last burn binance did where after burning over 600 million dollars worth of bnb coins, BNB price dropped in the market, people have grown with this mindset that any time a coin is burn, it always increases in value, NO, coins that are already very successful will hardly show any positive sign to burning though it will definitely show in the long term, but for the short term, it's not always so.
