For example, on this site you can see trading with a step of 5 minutes - https://www.tradingview.com/chart/

I am interested in data US$ / BTC for a long period of time.

You can try it with Trading view.

Exporting becomes available as soon as chart data is loaded. Scroll left to add more data to the chart, or drag the x-axis, then download.

But with too short time frame like 5-minutes chart, you don't need to download data too deep to the past like years ago. It's unnecessary.

Very old Bitcoin price data is there

For 5 min data, a few years worth of data is all you need.

They'll be so many 5 min candles that you'll have a decent sample size for analysis.
