Some users have suggested some videos in the above post so I am not going to repeat the same.

However me being an old skool person, always prefers to read more than watch. There are old and renowned books on stock market and technical analysis which you can read and get a glimpse of who the system works. I am stressing on reading stuff related to stock market first because a background in the same will help you a lot when entering crypto trading.

Most crypto youtube channels are going to shill altcoins, not bitcoin - so you need to be immune to that koolaid.

Other than that, try dummy trading at home and see how it goes. Remember that you can still make money without doing TA if you are going for a long term hodl. Watch the charts and buy at low - sell at high in a few years.
