There is a situation. I want to check the candlestick chart, the coin price, and the market cap of a certain coin on a specific date in the past, for example, I want to know the Ethereum market cap on December 20, 2021. How can I find this information? Where can I look it up?

Or help me ask in major live streams if anyone knows. I’m too shy to ask directly, no tricks, no insults, just learning. If you know, just tell me; if not, don’t pretend you do. Don’t act like you know when you don’t!
When asking, remind me to subtract the total supply and any recent issuance or burn mechanisms, like burning mechanisms, from the total supply on that day. Combine that with the coin price at that time to calculate the market cap at that time. I want that market cap. Don’t just tell me the current coin price or market cap now. If you do the math, you’ll get the market cap at that time!
I’ll give you a big tip.
Once I understand this, I can refute the paradox “the current coin price is cheaper than the last cycle,” a false proposition. I want to see if I bought a cheap coin price or a cheap market cap.
Quick, I need help. I’ve been strong all my life, but I bow to you now. Please help me, friends.
