by TC do you mean technical analysis?

There are many course on udemy you can get for free, as well as youtube for the basics
I'd recommend learning these concepts, candlesticks, market psychology basics, trend lines, patterns, RSI, MACD, Moving averages and elliot waves. Good luck!

I learned a lot of my style from NodeInvestor (from YouTube)- he also has a channel here but he doesn't upload as often as he does on YouTube. He is a fantastic very experienced trader that moved over to the crypto markets after decades of trading traditional stocks. He is a TA genius!
