Looking for Tick-Level Data for Top 100 Crypto Assets for Backtesting

Hello everyone,

I am in search of tick-level data for the top 100 crypto assets by market cap, including spot pairs (e.g., ETHUSDT), futures pairs (e.g., ETHUSDT.P), and BTC pairs (e.g., ETHBTC). I need this data to perform comprehensive backtests.

I've found that platforms like CoinMarketCap provide this data for around $15,300 per month or $110,000 per year, which is beyond my budget. My options are either to purchase one month of data and build on it or to gather this data directly from exchanges.

If anyone has experience with obtaining such data or knows of more affordable solutions, I would greatly appreciate your insights. Additionally, if there are any tools or services that can help streamline this process, please let me know.

Thank you!
