The high volume increases volatility, but you should also take a look at the OI as it affects the coin.
Most of the crypto has a fake volume, which means that market makers use their algorithms to provide liquidity to their clients.
You can use volatility as an indicator that the coin is active in the market. Such fluctuations can be exploited by trading bots, like grid bots, to capitalize on significant price movements.
Additionally, rising volatility in a flat market can signal an impending surge in the coin’s value. For instance, if trading volume jumps from 500k to 1 million while the market remains stable, it could indicate that a substantial price movement is on the horizon.
