Are you sure you are using Binance or another exchange? Binance supposed to show on the chart, but I did not see it on your chart.
I have gone through bitcoin chart on Binance anonymously, I was able to see the chart and I saw on both spot and future chart that you are not right, I can see high amount of transactions (bitcoin trading volume on the exchange in USD) under 1 minute chart.

Binance doesn't operate in my region so I use apps like Tabtrader and Tradingview for charting.
Btw, zero volatility doesn't mean there are zero trades, it means those trades basically didn't the move the price even a little bit (they all occurred at the same price).
Specifically went and made a screenshot from the Binance website for you.
Another example but from Tradingview:

As you can see the the high and the low of the candle differ by just 1 (one) cent. And those are 15 minutes candles!
