Picking a strategy - Crypto (Day trade)

Hey Team
I am new here! I just wanted to get one thing straight with the learning course I have reached lesson 5 now and wanted to know do I go through all the strategies and pick the best one or do I learn one and stick to it?

If the case is to pick a strategy, I'd need your help family. can someone here tell me. Which strategy is the relatively easiest to learn.

Which one is the most effective (profitable) - even if it's complicated and also if the choice doesn't matter and I should just pick one, still your input is appreciate in my learning journey

Thank you!
