Depends on which coin.  If the coin is a top-rated coin according to Coinmarketcap, then it's good to buy before the burn. For the short-term trade, it's a good strategy to make some easy buck. When the CEO of Binance exchange CZ announces any burning date, BNB coin pump hard. It's the same for FTX also. A few months ago NWC team also burned a lot of NWC coins and when the announcement came NWC pumped hard. I also earned a few bucks for the burning news. But dont forget to use stop-loss because some bag holders also dump their bags in this kind of news/announcement.
