Certainly, events like a massive coin sale, coin burns, and the creation of new tools for a blockchain can indeed affect the price of cryptocurrencies. These events can lead to significant price movements due to changes in supply and demand dynamics within the crypto market. For instance, a coin burn could reduce the total supply of a cryptocurrency, potentially increasing its scarcity and driving up its value. Similarly, the introduction of new features or tools to a blockchain can enhance its utility, which might lead to increased demand for the associated cryptocurrency. These events showcase how fundamental changes within a cryptocurrency's ecosystem can impact its price.
