How useful is Volume/Market Cap ratio when selecting a coin?

Basically the title.

I’m looking at AI coins like 0x0, GPU, HashAI and PAAL AI that I like but their volume/mcap ratios are abysmally low which makes me worried to touch them.

One one hand, I feel a higher ratio is nicer since it likely means more liquidity to enter and exit positions, while signalling positive market interest in the token.

On the other, I feel this volume is likely manipulated anyway and just signals speculation, which could cause it go both up or down. A lower volume could also mean increased utility and holding strength, which are both bullish. But again, that could mean just a small amount of capital is required to manipulate the price (eg: wash trading).

What are your thoughts? Is this metric useful? If so, how do you read / use it?
