actually the news is sometimes right and sometimes wrong, or rather the moment you take when you hear the news that a coin is holding an event, that's where your speculation assesses or estimates the price will go up or down, you should see starting from the daily volume increasing / decreasing, the price which slowly rises or not.
You made zero sense. Coin events no longer have any market impact, anyway. Everyone has become wise to the fact that all these news of partnerships, new blockchain, migration, burn etc all no longer mean anything if the coin is shit anyway.
Volume is also manipulated especially with coins that only belong to a few big wallets,,, and even if they are distributed true owners are the same.
Believe only what is objective and neutral.
