Need Historical Bitcoin (BTC) OHLC Candle Data (2007–2026) for Backtesting & Research

​

Hi everyone,

I'm working on a backtesting and market research project and I'm looking for historical Bitcoin (BTC) OHLC candle data covering the period from 2007 to 2026.

I'm mainly looking for any of these timeframes:

5-minute (preferred)

15-minute

30-minute

1-hour

CSV or Excel format would be perfect, but any commonly usable format is fine.

If anyone already has this data and is willing to share it, I'd really appreciate it.

If you don't have the data but know a reliable source, archive, exchange, or website where I can get it (free or paid), I'd be grateful for your suggestions as well.

The data will be used only for backtesting, market research, and educational purposes.

Thanks in advance for your help
