Hodling Bitcoin for the long term is not the same as trading it. If your main goal is to hold onto and gather as much Bitcoin as you can, learning about the technical analysis of Bitcoin might not be necessary. It's not a bad thing to learn, but it might make it challenging to save and hold onto your Bitcoin for a long time if you're constantly using your funds to trade, and trading involves risks with no guaranteed profits. Someone investing in Bitcoin should focus on securing their funds as that's the most important thing every Bitcoin investor should understand.
